Syrian rebels have seized a border crossing with Israel, activists said.
It is the first time the rebels had seized a border crossing next to the Israeli occupied Golan Heights but it was unclear whether the fighters would be able to hold the site, the British-based Syrian Observatory for Human Rights said.
Israel is concerned that the Golan, which it captured from Syria in 1967, will become a springboard for attacks by jihadi fighters, who are taking part in the struggle against Assad.
Rami Abdelrahman, head of the Observatory, said: "The rebels have seized the crossing near the old city of Quneitra in the occupied Golan Heights. There are heavy explosions and fierce clashing ongoing in the area."
