Battle for Kobane: Before and after images

Kurdish forces, backed by US-led air strikes, are continuing to fight Islamic State militants in the northern Syrian town of Kobane. The battle is regarded as a major test of whether the coalition's air campaign can push back the jihadists.

Activists say more than 600 people have been killed since the group launched its assault on the mainly Kurdish town a month ago.

Satellite imagery, released by the UN's Institute for Training and Research (Unitar), reveals how Kobane is suffering amid the conflict. Analysis shows a build-up of vehicles near the Turkish border, widespread building damage as well as a refugee camp set up to accommodate those fleeing the fighting.
