Jerusalem - An Israeli tank fired a warning shot on Sunday for the second time in 24 hours at a Syrian army post in a buffer zone on the Golan Heights, the army said.
Although the post was on the Syrian-controlled side of the strategic plateau it was undergoing construction work forbidden by a separation of forces agreement between the sides, a military statement said.
Warning shot
It said Syria's armed forces "violated the 1974 ceasefire agreement by conducting construction work to strengthen a military post in the northern part of the demilitarised zone.
"In response, the Israel Defence Forces fired a warning shot towards the area using a tank.
"The agreement prohibits the entry of heavy construction tools or military vehicles into the demilitarised zone," it said, without giving the precise location of the incident.
A tank on Saturday also fired a warning shot and the army issued an almost identical statement.
Annexed it
But it also said it had filed a complaint with the UN Disengagement Observer Force (UNDOF) which monitors the line between the Syrian and Israeli-held sectors.
Israel seized 1 200km2 of the Golan Heights from Syria in the Six-Day War of 1967 and later annexed it in a move never recognised by the international community.
