Israel says its soldiers have fired artillery into Syria in response to gunfire aimed at its troops in the Israeli-controlled Golan Heights.
There were no reported injuries on the Israeli side from the shootings.
Reuters reports it is the third case this month of violence seen as a spillover of civil unrest in Syria that has also alarmed other neighbours such as Lebanon and Turkey.
The Israeli military has lodged a complaint with the United Nations on the incident.
The U.N. has a peace-keeper force in the area monitoring a ceasefire in place since the 1970s.
Israel captured the Golan area in a 1967 war and later annexed it in a move never recognised internationally.
