UN monitors 'shot at in Syria,' says Ban Ki-moon

The head of the UN says monitors trying to reach the Syrian village of Qubair, where 78 people are said to have been killed, were shot at with small arms.

Addressing the UN General Assembly, Ban Ki-moon condemned the reported massacre as "shocking and sickening", and an "unspeakable barbarity".

UN monitors said earlier that Syrian troops had blocked access to Qubair.
