Israeli and Syrian forces have exchanged fire across the ceasefire line in the occupied Golan Heights.
Israel returned fire after one of its military vehicles was hit by shots from Syria, Israel's defence forces say. Media reports say no-one was hurt.
Syria says it destroyed an Israeli vehicle which it says crossed the ceasefire line into territory its forces control.
Syria and Israel have traded fire a number of times in recent weeks.
The Israeli military said its troops "returned precise fire" after the vehicle was hit.
A statement from the Syrian army said it had "destroyed an Israeli vehicle with everything that it had in it". The statement said the vehicle was shot after it crossed the ceasefire line and headed towards the rebel-held village of Bir Ajam. It warned that any attempts to violate its sovereignty would be "met with immediate and firm retaliation".
Syrian President Bashar al-Assad has previously accused Israel of aiding the rebels, but has not provided substantive evidence.
Speaking after Tuesday's incident, Israeli chief of staff Lt Gen Benny Gantz said Israel would not allow the Golan to become "a comfortable sphere for Assad to operate from", warning the Syrian leader would "bear the consequences" if the situation deteriorated.
