Putin's withdraw of Russian troops from the Ukraine border has lowered morale among pro-Russian separatist fighters in Ukraine. "Why does he betray us? He gave us hope to fight, and then gave us up. When he moved his troops, people lost hope," said Dmitry Boitsov of the Russian Orthodox Army, a newly formed militia group in Ukraine's turbulent east. Fighting in Slaviansk, Ukraine has been fierce over the last couple of days, with 50 separatists from the Donetsk People's Republic killed in the past 24 hours.
