Israel has fired retaliatory warning shots into Syria after a mortar round hit an outpost in the Golan Heights, the Jerusalem Post has reported.
No damage or injuries have been recorded.
The Israeli Defence Force have acknowledged that the mortar was not aimed at the outpost but was fired as “part of the internal conflict inside Syria”.
Israel annexed the Golan Heights from Syria in 1967
Earlier on Sunday, Israeli Defense Minister Ehud Barak warned Syrian attacks on the Golan Heights would be met with a military response saying: "If a shell falls, we will respond."
It comes just over a week after Syrian tanks strayed into the UN patrolled demilitarised buffer zone between the two countries, as tensions in the region increase.
Israel's military chief, Lieutenant-General Benny Gantz, said last week: "This is a Syrian issue that could become our issue."
It is the first Israeli milltary action against Syria since the 1973 Yom Kippur War.
The two countries are still formally at war with each other and there are major fears that Syria's civil conflict could spill over into the highly volatile region.
The IDF filed an oficial complaint to the UN, reports the BBC, saying that any further fire "shall be responded to with severity".
Home Front Defense Minister Avi Dichter has warned of the dangers of over-reacting describing how "nerves of steel" and "a level-headed response from Israeli authorities" are required.
