A member of the U.N. Disengagement Observer Force (UNDOF) keeps watch of the Syrian side of the Quneitra crossing from an observation post in the Golan Heights August 28, 2014. Syrian jets shelled rebel positions near the border crossing close to the Israeli-occupied Golan Heights that was seized by rebels in some of the heaviest clashes in the strategic area this year, rebels and residents said on Thursday. A U.N. spokeswoman earlier said the organisation's peacekeepers could not confirm whether the rebels had seized the crossing, "as fighting is ongoing" at one of its gates.
