The delivery of humanitarian aid to half a million displaced civilians in north-eastern Syria is under threat from fighting between Iraqi forces and Kurdish fighters near the border, a medical charity has warned.
Doctors Without Borders is "extremely concerned" because the fighting threatens its only cross-border supply routes between the two countries - the Fishkhabour crossing.
Scattered clashes erupted in recent weeks as Iraqi forces retook disputed territory from the Kurds, part of a crisis sparked by last month's Kurdish vote for independence.
Federal forces sought to regain control of the country's borders from forces loyal to the Kurdish regional government.
At least 11 civilians were killed in government bombings of a rebel-held enclave north of the capital Damascus, said Syrian activists. Two women, a child and a media activist working for local TV were among those killed in the Saqba and Hamouriyah districts, it has been reported.
