Gunfire from Syria hit the Israeli-occupied Golan Heights overnight close to an Israeli military vehicle monitoring the ceasefire line but causing no injuries, the military said on Monday.
"There was gunfire near an Israeli military vehicle which was driving along the security fence," a military spokeswoman said, adding the incident had occurred late on Sunday.
But she said troops in the area had not returned fire as they have done on previous occasions.
Such incidents have occurred with increasing frequency in the past few weeks as violence from the civil war in Syria spills across the ceasefire line.
Earlier this month, Israeli troops fired warning shots and tank shells across the UN-monitored ceasefire line in response to Syrian fire, in the first instance of Israeli fire directed at the Syrian military in the Golan Heights since their 1973 war.
Fears of a spillover of the conflict which has ravaged Syria for the past 20 months and left more than 40,000 dead, have widened as violence has spread to Syria's borders with Turkey, Lebanon, Jordan and Iraq.
