Syrian jets shelled rebel positions near a border crossing close to the Israeli side of the Golan Heights, rebels and residents told Reuters overnight Wednesday.
Al-Qaeda's Syria wing, the Al-Nusra Front, alongside moderate rebel groups who had launched the attack early on Wednesday on the border post were "holding ground" despite the heavy bombardment, according to a source in the Islamist Beit al Maqdis brigade, whose fighters were involved in the fighting.
Abu Iyas al Horani, a spokesman for another rebel group operating in the area, told Reuters that at least six rebels were killed in the latest spillover of violence in the area that lies almost 20 kilometers west of the town of Quneitra.
The reports of the aerial attacks come hours after two incidents on Wednesday in which fire from the civil war in Syria spilled over to the Israeli side.
On Wednesday morning, six mortar shells careened into Israeli territory from the Quneitra area, lightly-to-moderately wounding an IDF officer and causing damage to several vehicles.
In response to the mortar shells, IDF artillery fired at a Syrian military position.
Later in the day, one Israeli was lightly wounded by tank fire in the area, after a possibly errant shell struck an Israeli community in the region.
The Syrian Observatory for Human Rights said 20 Syrian soldiers and 14 rebel fighters were killed in the clashes between the sides. The organization gathers information from all sides in the Syrian war.
The United Nations referred to the shells fired from Syria which hit the Israeli side of the Golan Heights and called on all sides to “exercise restraint”.
