"It is quite clear to me that this war is unlikely to end by the fall," Arestovich said on Ukrainian TV, NBC News reported. It comes as President Volodymyr Zelenskyy seeks to extend martial law for another 90 days.
In some positive news, the U.S. Congress cleared $40 billion in aid for the war-torn country. It now goes to President Joe Biden for his final signature.
Failure to reopen Ukrainian ports would be a declaration of war on global food security: World Food Programme
A failure to open Ukrainian ports would be a declaration of war on global food security in this "unprecedented crisis," warned the World Food Programme's executive director, David Beasley.
"Food pricing is our number one problem right now, as a result of all this perfect storm for 2022," Beasley said. "But by 2023 it very well will be a food availability problem."
Ukraine is a major exporter of agriculture, feeding about 400 million people globally, according to WFP.
WFP's analysis found that 276 million people globally were suffering from acute hunger at the start of 2022. If the war continues, that number could rise by 47 million.
Because ports in Ukraine have been blocked as a result of the war, millions of metric tons of grain cannot be shipped out, the WFP said.
Ukrainian farmers won't have anywhere to store the next harvest in July or August if ports are not reopened, which means the grains will go to waste while the world struggles with a global food crisis, WFP said.
Food prices have soared since Russia invaded Ukraine in late February. Food prices are at the highest levels ever recorded by the United Nations Food and Agriculture Organization, up 34% from this time last year.

Blinken slams Russian claims that sanctions have caused mounting food crisis
U.S. Secretary of State Antony Blinken slammed Russian claims that U.S. sanctions, rather than Moscow's invasion of Ukraine, triggered the worsening global food crisis.
"Sanctions aren't blocking Black Sea ports, trapping ships filled with food, and destroying Ukrainian roads and railways; Russia is. Sanctions are not emptying Ukrainian grain silos and stealing Ukrainian farm equipment; Russia is," Blinken said before the United Nations Security Council.
"Sanctions aren't preventing Russia from exporting food and fertilizer," he said. He added that Moscow has chosen to weaponize these commodities.
Blinken added that the sanctions imposed by the United States and its allies have deliberately included "exceptions for food, fertilizer and seeds from Russia." America's top diplomat reiterated calls for Russia to stop "blockading the ports in the Black Sea and the Sea of Azov and to allow for the free flow of ships and trains and trucks carrying food out of Ukraine."
"Stop preventing food and other lifesaving supplies from reaching civilians in besieged Ukrainian towns and cities," he added.

U.S. Chairman of the Joint Chiefs of Staff speaks with Russian counterpart
Chairman of the Joint Chiefs of Staff U.S. Army Gen. Mark Milley spoke with his Russian counterpart via phone, the Pentagon confirmed.
"The military leaders discussed several security-related issues of concern and agreed to keep the lines of communication open," Milley's spokesman U.S. Army Col. Dave Butler wrote in a summary of the call with Chief of Russian General Staff Gen. Valery Gerasimov.
"In accordance with past practice, the specific details of their conversation will be kept private," Butler added.
The call comes a week after Secretary of Defense Lloyd Austin held a phone call with his Russian counterpart, the first known discussion since Russia's invasion of Ukraine.

Davos returns from pandemic, but without Russian guests
After a nearly 2-1/2-year hiatus because of the coronavirus pandemic, the Swiss town of Davos is set to again host global elites from business, government and activist groups for the World Economic Forum.
Russia's war in Ukraine and climate change worries are expected to be on many minds at the event starting Monday as concern over the pandemic ebbs.
Ukrainian President Volodymyr Zelenskyy plans to pipe in virtually. The biggest delegation of top Ukrainian government officials to leave the country since the war started are set to attend Davos in person, organizers said. In the wake of Russia's invasion of Ukraine, forum hosts invited no Russian officials or business leaders this year.
"I'm positive that that was the right decision," forum president Borge Brende said during a news conference Wednesday. "We do hope, though, that Russia will follow a different path … in the years to come, to start to stick to the U.N. Charter and to their international obligations."

Biden says Sweden and Finland have complete support from U.S. to join NATO
President Joe Biden, flanked by the leaders of Sweden and Finland, said both nations have the "full backing" of the United States in their bid to join NATO.
Biden's remarks come on the heels of filed applications by both Sweden and Finland to join the world's most powerful alliance.
Both Finland and Sweden already meet many of the requirements to be a NATO member, like having a functioning democratic political system, willingness to provide economic transparency and the ability to make military contributions to NATO missions.
However, all 30 NATO members must give unanimous approval for a country to be accepted into the alliance.

NATO increases air policing flights over eastern flank
NATO Secretary-General Jens Stoltenberg praised Denmark's security contributions to the military alliance during a meeting with Danish Prime Minister Mette Frederiksen. Stoltenberg namely applauded Danish support in air policing missions over NATO member countries in the east.
From fighter jets to surveillance aircraft, the NATO alliance has placed up to 30 aircraft on patrol over the skies of its eastern flank. The additional flights come as Russian officials warn of "grave consequences" for any NATO expansion, including the recent applications from Finland and Sweden to join the military alliance.
So far, the U.S. has committed the most types of aircraft to complement the alliance's security mission.
Here's an overview of the NATO member aircraft flying the skies:

UN says at least 3,811 killed in Ukraine since start of war
The United Nations has confirmed 3,811 civilian deaths and 4,278 injuries in Ukraine since Russia invaded its ex-Soviet neighbor on Feb. 24.
The Office of the U.N. High Commissioner for Human Rights said the death toll in Ukraine is likely higher, because the armed conflict can delay reports.
The international body said most of the civilian casualties recorded were caused by the use of explosive weapons with a wide impact area, including shelling from heavy artillery and multiple launch rocket systems, as well as missiles and airstrikes.

Hundreds of Azovstal prisoners of war registered, Red Cross says
The International Committee of the Red Cross has said it continues to register prisoners of war from the Azovstal steelworks plant in Mariupol, and has registered hundreds already this week.
The ICRC started to register combatants leaving the Azovstal plant on Tuesday, including the wounded, with the operation continuing through to today. It did not give an exact number of how many soldiers had been registered.
The Red Cross noted that it is not transporting POWs to the places where they are held, with Russia reporting yesterday that it had transferred 900 Ukrainian fighters from the plant to a former prison colony. It's unknown what will happen to the fighters.
The Red Cross says it has been collecting vital personal information from the fighters who have been captured in a bid to help them keep in touch with their families.
In accordance with the mandate given to the Red Cross by the 1949 Geneva Conventions, it said it must have immediate access to all POWs in all places where they are held. The ICRC must be allowed to interview prisoners of war without witnesses, and the duration and frequency of these visits should not be unduly restricted.
Whenever circumstances permit, each party to the conflict must take all possible measures to search for and collect the dead.
Russia forces focus fighting on Donetsk, Ukraine says
Ukraine's armed forces have said the main focus of Russian fighters is on Donetsk in eastern Ukraine.
In the latest operational update posted on Facebook, Ukraine said 16 Russian attacks were repulsed in the Donetsk and Luhansk directions last night with eight Russian tanks, 17 units of armored combat vehicles, four special armored vehicles and six conventional enemy vehicles destroyed.
They also said Russian forces were trying to regain lost positions around the major city of Kharkiv in northeastern Ukraine. Earlier in the week, Russian forces were driven back as far as the border.
Ukraine claimed that Russia was looking to involve university students in occupied Donetsk "in hostilities" in the absence of other resources that could be mobilized. The information was not able to be verified.

Vyshyvanka Day in Ukraine
Ukraine's President Volodymyr Zelenskyy has wished his compatriots all the best for Vyshyvanka Day, a national day celebrating Ukraine's folk traditions and culture with the national costume, the embroidered traditional dress called the "vyshyvanka."
"I wish you health. Strong, unbreakable, brave and free. Happy Vyshyvanka Day, Ukraine!," Zelenskyy said on his Telegram channel today, while sporting his own embroidered shirt.
The day, traditionally celebrated on the third Thursday of May every year, has more resonance this year as it takes place as Ukraine remains under attack from Russia.

Cease-fire in Ukraine impossible unless Russia withdraws all troops, official says
One of Ukrainian President Volodymyr Zelenskyy's advisors has said that a cease-fire in Ukraine is impossible unless all Russian troops withdraw.
On Twitter Thursday, Mykhailo Podolyak said: "do not offer us a ceasefire - this is impossible without total Russian troops withdrawal."
Ukraine is not interested in new "Minsk" accords and a renewal of the war in a few years, he said, referring to several failed agreements which aimed to end the conflict in the Donbas region of eastern Ukraine —between pro-Russian separatists and Ukrainian forces — that had been going on since 2014 before Russia's wider invasion.
Until Russia "is ready to fully liberate occupied territories, our negotiating team is weapons, sanctions and money," he said.

Moscow is firing senior commanders for battlefield failures, says British government
Moscow over recent weeks has fired senior military commanders for failures in Russia's invasion of Ukraine.
The U.K. Ministry of Defence pointed to Lt. Gen. Serhiy Kisel, whose forces failed to capture Ukraine's second-biggest city, Kharkiv. Also suspended was Vice Admiral Igor Osipov, who commanded the Black Sea Fleet until its flagship, the Moskva, was sunk in April.
Valeriy Gerasimov, Russian Chief of the General Staff, "likely remains in his post," but it's unclear whether President Vladimir Putin retains confidence in him.
The press office of the Russian defense ministry did not immediately respond to a request for comment.
In an intelligence update, the British ministry predicted that Russia will face difficulty regaining the initiative in its war against Ukraine, because generals and other officials will want to seek cover by deferring to their superiors on key decisions.
"Many officials involved in the invasion of Ukraine will likely be increasingly distracted by efforts to avoid personal culpability for Russia's operational setbacks," the Ministry of Defence said.

Russia says it has sent 900 Ukrainian soldiers to former prison colony
Russia said 900 Ukrainian soldiers have been taken to a former prison colony, in a Russian-controlled part of Donetsk.
Speaking on Wednesday, Russian Foreign Ministry spokeswoman Maria Zakharova said, citing Russia's defense ministry, that 959 Ukrainian fighters, including 51 with severe wounds, "have laid down their arms over two days."
While the injured were receiving medical care at a hospital in the pro-Russian "Donetsk People's Republic" in the Donbas region of east Ukraine, "the rest were sent to a pre-trial detention center," she said, in Olenivka, where a former prison colony is located.
On Monday, Ukraine's human rights ombudsman said on Telegram that the Russian military was holding more than 3,000 civilians from Mariupol at the former penal colony with some subjected to interrogation and torture, she said. The information is unverified, however.
The soldiers had been holed up in the Azovstal steelworks plant in Mariupol and had been evacuated earlier this week and taken to Russian-controlled territory. There were expectations that they could be exchanged for Russian soldiers in Ukrainian control but that's uncertain.
Ukraine has said there are more of its fighters left in the Azovstal steelworks but has not said how many.
The complex was seen as the last stronghold of Ukraine's forces in the southern port city — one that Russia has aimed to control from the start of its invasion on Feb. 24 and which is seen as a strategic objective for Moscow as it aims to create a land bridge from Russia to Crimea, which it annexed in 2014.
Ukraine said its soldiers had been "evacuated" while Russia claimed they had "surrendered."

Biden optimistic about Finland and Sweden joining NATO, despite Turkey's concerns
U.S. President Joe Biden sounded optimistic that Turkey can be persuaded to support Finland and Sweden in their bids to join NATO.
"I think we're gonna be okay," Biden told reporters when asked if he could convince Turkey to change its mind.
Biden's remark came two days after Turkish President Recep Tayyip Erdogan doubled down on his country's opposition to the two new candidates for the international security alliance.
The White House nevertheless echoed Biden's optimism at a press briefing.
"We're confident that at the end of the day, Finland and Sweden will have an effective and efficient accession process, [and] that Turkey's concerns can be addressed," said Biden's national security advisor Jake Sullivan.
He noted that U.S. Secretary of State Antony Blinken was in talks with his Turkish counterpart. "We feel very good about where this will track to," Sullivan said.

U.S. reopens embassy in Kyiv after closing it for three months
The U.S. reopened its embassy in Kyiv after closing it for three months before and during Russia's invasion of Ukraine.
"When we suspended operations at the embassy, we made the point clear: while we would relocate U.S. embassy personnel for their safety and security, this would in no way prevent our engagement with and support for, the Ukrainian people, government and civil society as well as our allies and partners," Secretary of State Antony Blinken wrote in a statement.
As it raised the American flag over the compound, the U.S. became the latest Western country to resume diplomatic operations in Kyiv.
Blinken said the U.S. enhanced security measures and protocols at the embassy ahead of the reopening and return of American diplomats.
