Israeli soldiers have opened fired on pro-Palestinian protesters in Syria as they marched on the Israeli-occupied Golan Heights.
Israel had vowed to prevent a repeat of a similar march last month, in which hundreds of people had managed to breach the border fence.
Witnesses said several people appeared to have been injured. Syrian state TV said four people had died.
The protesters were marking the 44th anniversary of the 1967 Mid-East war.
Earlier, Israeli Prime Minister Benjamin Netanyahu said he would not allow "extremists" to breach Israel's borders.
"I have instructed our security forces to act with determination and restraint in order to protect our sovereignty our borders, towns and citizens," he said at the weekly cabinet meeting in Jerusalem.
But this did not deter several hundred demonstrators from moving on the razor-wired fencing and freshly dug trenches close to the frontier village of Majdal Shams in the Golan Heights at around noon.
