Thirteen people have been killed and at least 45 wounded following a bomb blast in northern Yemen.
The bomb hidden in a motorcycle exploded outside a mosque in the city of Saada this morning.
Worshippers, including army officers, were leaving the Bin Salman Mosque after Friday prayers when the blast occurred.
Military personnel are usually among the faithful at the mosque, which like others in Yemen caters for both the majority Sunni community and Zaidis, a Shia offshoot.
It is not known who planted the bomb near the door of the mosque, but the northwestern province has been rocked by sporadic violence since a conflict broke out between government forces and rebels in 2004.
Hundreds of people have been killed and thousands have fled their homes in Saada since the conflict began.
Seven Yemeni troops were killed on Tuesday in an ambush by the rebels, who often clash with troops of the US-allied Yemeni government and tribes loyal to it.
