Syria crisis: UN observers 'under fire in Homs'

Footage had emerged that appears to show UN observers coming under fire in the Syrian city of Homs.

Shots can be heard in the video, which was posted online, but it not clear who was firing them.

A small UN team is currently in Syria as part of efforts to monitor a fragile ceasefire between government and rebel forces.

Meanwhile, the Security Council has voted to increase the number of UN observers in the country to 300 for three months.
