SANA'A, July 11-Saudi-led air strikes hit locations in Sana'a two hours after the humanitarian truce came into effect.

Eyewitnesses said the airstrikes pounded Al-Hafa military camp to the east of Sana'a and the headquarters of the Military Work Department in Sawan area of Sana'a, causing huge explosions.

The one-week U.N.-brokered truce started midnight Friday with the purpose of the deliveries of aid to Yemen, a move to alleviate the suffering of the people after three months of devastating war.
