Kurdish peshmerga fighters open fire on Islamic State targets in Kobani, in this video obtained from social media.

Male and female brigades are working together to defeat the militants who have dug in to seize control of the Syrian border town.

But Islamic State is proving resilient.

Despite a coordinated bombing campaign by a US-led coalition, and the ongoing fight with peshmerga forces on the ground, the militants have surrendered little of their self-declared caliphate, pledging to defend Kobani street by street.
