Rebels seized a U.N.-operated border crossing linking Israel and Syria, activists said, following heavy clashes on the Golan Heights on Thursday between the opposition and President Bashar al-Assad's forces.
It is the only crossing between the two countries and it was the first time Syrian rebels had managed to take the place. However, it was unclear if they could hold it for long, with fighting still raging in the area.
Israel is worried that the Golan, which it captured from Syria in 1967, will become a springboard for attacks on Israelis by jihadi fighters, who are taking part in the armed struggle against Assad.
Officials from the United Nations Disengagement Observer Force, which operates the base, could not be reached for comment.
