Putin: 'We can work with US on Syria'

US President Barack Obama and his Russian counterpart Vladimir Putin have met in New York, on the sidelines of the UN General Assembly, after delivering speeches that exposed sharp differences over how to tackle the Syrian crisis.

Speaking after their meeting, Mr Putin said Russia might be willing to join air strikes against the Islamic State group if they were backed by the United Nations. But he ruled out Russian troops ever taking part in a ground operation in Syria.

He said he thought there was a chance for the US and Russia "to work out our differences together".
