WASHINGTON -- The United States "strongly condemned" Hezbollah's rocketing of Israeli territory on Wednesday with anti-tank munitions, killing two IDF soldiers and wounding seven others.

"The United States strongly condemns Hezbollah’s attack today on Israeli Defense Forces (IDF) near the border between Lebanon and Israel," said Edgar Vasquez, a State Department spokesman, "in blatant violation of UN Security Council Resolution 1701."

"We don’t have information on what munitions were used by Hezbollah," Vasquez added, when asked for comment on Hezbollah's alleged use of sophisticated anti-tank, Russian-made Kornet rockets.

On Tuesday, the State Department warned against "escalation" on Israel's northern border, after Syrian positions fired into the Golan Heights. The Israeli air force returned fire on Syrian Army positions overnight.

United Nations Resolution 1701 codified a ceasefire over the blue line between Israel and Lebanon after Israel's conflict with Hezbollah in 2006.

"We support Israel's legitimate right to self defense," State Department spokeswoman Jen Psaki told reporters on Wednesday, urging both parties to "respect the blue line between Israel and Lebanon."

"We also of course condemn the act of violence, and will be watching the situation closely," Psaki said.

The Israeli military authorities have been on high alert the last 10 days following the attack on a convoy carrying Hezbollah and Iranian officials on the Syrian side of the Golan Heights earlier this month.

Hezbollah has vowed to avenge the attack, which it blames on Israel.

Following the anti-tank missile, mortar shells launched from Syria were fired at IDF positions on Har Dov and the Hermon Mountain. 

The army evacuated dozens of people from the Hermon Mountain. A home in the Israeli border town of Kafr Rajar was damaged by a mortar shell.

The officer and soldier killed in the Hezbollah attack on the Lebanese border were named on Wednesday as Cap. Yohai Kalangel, 25 from Har Gilo, a company commander in the Tsavar Battalion and Sgt. Dor Haim Nini of the same battalion, a 20 year old from Shtulim who will be posthumously promoted to the rank of Staff-Sergeant.
