Islamist rebels attacked Somalia's parliament as it met for the first time this year, in clashes which led to the deaths of at least 11 people. Insurgents fired mortar bombs at the building in Mogadishu, triggering retaliatory shellfire from African Union peacekeepers. There were rowdy scenes in the chamber earlier as members voted to remove the speaker, who had criticised the PM. The rebels have fought a three-year war against the fragile interim government. They launched Sunday's attack from their stronghold in the capital's main market at Bakara.

More than 20 people were injured in the crossfire as AU soldiers guarding MPs fired back with artillery. Parts of Bakara market caught fire and several shopkeepers were killed, according to reports. Shortly beforehand, the parliamentary speaker, Sheikh Adan Madobe, urged Somali President Sheikh Sharif Sheikh Ahmed to appoint a new prime minister. MPs voted to sack the speaker and Prime Minister Omar Abdirashid Ali Sharmarke later accused him of treason.
