US and Turkey to boost operational planning for Syria

US Secretary of State Hillary Clinton has said a working group will be set up with Turkey to plan a joint response to the Syrian crisis.

After talks in Istanbul she said she had discussed with Turkey's foreign minister how best to support opposition to President Bashar al-Assad's rule.

The US, she said, was also increasing aid for Syrian refugees and thanked Turkey for supporting more than 50,000 Syrians who have fled the violence.
