US-led strikes kill 'several hundred' IS militants
John Allen, a retired four-star general and US envoy to the coalition fighting the Islamic State said US-led air strikes on a Syrian border town killed "several hundred" Islamic State fighters but it may still fall, acknowledging significant militant gains in Iraq and Syria.
While Iraqi troops prevented the militants from seizing a lynchpin provincial capital near Baghdad, a senior US envoy admitted IS forces have scored important advances in Iraq.
He said it would take time to build up local forces to defeat them there and in Syria.
In the border town of Kobane, Kurdish defenders backed by a flurry of US-led air strikes were reported to have stopped IS fighters from gaining ground and even recaptured some positions.
