Islamic State crisis: Besieged Kobane under heavy fire
Heavy fighting has been reported between Kurdish militiamen and Islamic State (IS) militants advancing on the northern Syrian town of Kobane.
A BBC correspondent across the border in Turkey saw explosions and smoke rising from buildings hit by shells.
The jihadists have moved to within a few kilometres of the Kurdish town on three sides despite US-led air strikes.
On Thursday, Turkey’s prime minister promised it would do whatever it could to prevent the fall of Kobane.
Ahmet Davutoglu spoke only hours after the Turkish parliament authorised military operations against militants in Iraq and Syria who threaten Turkey’s security, and for foreign troops to use Turkish bases.
