'Matter of time before Kobane falls to Islamic State'

The US-led coalition has carried out its most sustained air attacks so far on Islamic State fighters attacking the Turkey-Syria border town of Kobane.

Syrian Kurdish fighters said the strikes were the most effective yet but should have come much earlier.

BBC correspondent Jim Muir said most people thought it was a matter of time before Kobane fell - because air strikes would not be effective against IS fighters inside the town.
