Two soldiers were killed and seven wounded Wednesday after an Israeli military vehicle was hit by an anti-tank missile near the Israeli-Lebanese border, NBC News reported. A U.N. peacekeeper was also killed. Israel responded by firing at least 20 artillery shells into Lebanon. Hezbollah claimed responsibility for the attack. In a statement, the militant Islamist group said its attack was carried out by a division calling itself the "Heroic Martyrs of Quneitra" — a reference to an Israeli airstrike on the Golan Heights on Jan. 18 that killed six Hezbollah fighters. The clash came after Israel launched airstrikes earlier Wednesday targeting Syrian army artillery posts in response to rockets fired the previous day into the Israeli-held Golan Heights.
