Fighting is continuing around the Syrian border town of Kobane, with reports of fresh US-led coalition air strikes targeting Islamic State (IS).
Kurdish fighters say they are trying to push back the IS advance after what they called effective strikes.
The UN envoy for Syria has urged the international community to act now to prevent IS from seizing the key town.
Staffan de Mistura told the BBC that the fall of Kobane would be “a massacre and a humanitarian tragedy”.
Seizing the entire town would give the IS jihadists full control of a long stretch of the Syrian-Turkish border, which has been a primary route for foreign fighters getting into Syria, as well as allowing IS to traffic oil from oilfields it has captured.
