Syria: Kurdish army 'needs more support in Kobane'
Fierce fighting has erupted in the north of the Syrian town of Kobane, after two days of relative calm.
Kurdish fighters were thought to have pushed back Islamic State, preventing them from taking over the town. Kobane, on the Turkish border, which is a key objective for IS.
The renewed fighting came as Turkey said it would allow Iraqi Kurdish Peshmerga fighters to cross into Syria to fight IS.
Karwan Zebari, head of the Kurdish Regional Government mission to Washington DC, spoke to John Humphrys.
