MAJDAL SHAMS, Golan Heights (Reuters) - Israeli troops shot at Palestinian protesters on its frontiers with Syria, Lebanon and Gaza on Sunday, killing nine who were marking what they term the catastrophe of Israels founding in 1948. Troops opened fire in three separate border locations to prevent crowds of demonstrators, some lobbying rocks, from crossing Israeli frontier lines, in the deadliest such confrontation in years. Israel called it a cynical provocation inspired by Iran, to exploit Palestinian nationalist feeling fuelled by the popular revolts of the Arab Spring across the Middle East, and to draw attention from major internal unrest inside Syria, its ally. The Syrian foreign ministry condemned what it called Israels criminal activities, the state news agency SANA said. Syrian media reports said Israeli gunfire killed two people after dozens of Palestinian refugees infiltrated the Israeli-occupied Golan Heights from Syria, along a disputed border that has been largely tranquil for decades. Security sources on the nearby Lebanese frontier said six Palestinians died when Israeli forces shot at rock-throwing protesters to prevent them from entering the Jewish State. The Lebanese army had also earlier fired in the air in an attempt to hold back the crowds. On Israels tense southern border with the Gaza Strip, Israeli gunfire wounded 82 demonstrators approaching the fence with the Hamas-run enclave, medical workers said. In a separate incident, Israeli forces said they shot a man who was trying to plant a bomb near the border. A body was later found.
