Golan Heights (CNN) -- Israeli troops fired on protesters trying to cross the fortified border between Syria and the occupied Golan Heights on Sunday, with Syrian authorities reporting more than a dozen dead and hundreds wounded. The protests came on the anniversary of the 1967 Middle East War, when Israel captured the Golan Heights from Syria. The Israel Defense Forces did not immediately confirm any casualties, though a spokeswoman said that Israeli troops used tear gas and live ammunition on members of an "angered mob." "We warned them verbally (and) with warning shots into the air," Lt. Col. Avital Leibovich told CNN. "And when these two options failed, we had to open fire selectively into the area, and this actually stopped those Syrians from reaching the Israeli-Syrian fence."
