Shell fire kills at least 30 in Mogadishu

Mortar bombs killed at least 30 people in Somalia's capital Mogadishu on Thursday after rebels launched shells at the president's plane and African Union (AU) peacekeepers responded with heavy artillery fire.

President Sheikh Sharif Ahmed, who was leaving for a summit in Uganda, was not hurt. But residents and medical workers said at least 30 people died and scores more were wounded in one of the heaviest exchanges to rock the city for weeks.

Farah Olow, a shopkeeper in the sprawling Bakara market, told sources by telephone that six people were killed by a shell that demolished a home there.

"They were taking cover in a concrete building, but such big shells can penetrate the strongest house," he said. "We can't go out to count how many more are dead. Bombs are raining on us."

Bakara, which is notorious for its open-air weapons bazaar, has long been viewed by the government and the AU force AMISOM as a stronghold of hardline Islamist al Shabaab insurgents trying to overthrow the country's transitional administration.

Washington accuses the rebel group of being al Qaeda's proxy in the failed Horn on Africa state.
