Syria crisis: Blast near Damascus military compound

A large explosion has struck close to a military compound in the Syrian capital, Damascus, near a hotel used by the UN's observer mission.

Syrian state TV reported that three people had been injured in the blast, but that none of them were UN monitors.

The intended target of the explosion was not immediately clear.

Meanwhile UN humanitarian chief Valerie Amos, who is visiting Syria, has said it should be made easier for aid to be delivered to civilians who need it.
