On the ground in the besieged city of Kobani, images taken from social media purportedly show the devastation inside the Syrian town near the Turkish border. It has been under attack from ISIL fighters for more than three weeks.
ISIL is said to control around half of the town including key buildings in the security quarter. The insurgents could be seen moving around the northeast to complete their encirclement.
US-led airstrikes have intensified in recent days, but the White House admits that air strikes alone are not going to save Kobani.
Under pressure to act, Turkey has agreed to train and arm moderate Syrian opposition groups following talks with Washington.
Turkish tanks remain poised on the border, Ankara says any intervention hinges on support from the international community.
