At least three people are killed and 10 others injured on Tuesday in fresh shelling that rocked parts of Somalia's restive capital Mogadishu, medics and witnesses said.

Witnesses said clashes erupted in Mogadishu's Yaqshid neighbourhood where several mortar shells fired by government forces landed at residential areas and market, killing at least five civilians and injuring more than 10 others.

Several wounded civilians were admitted in various Mogadishu hospitals, according to ambulance workers.

"We collected 10 wounded people from areas that were mostly shelled. These areas include Bakara, Hararyale, Suuq Ba'ad and Sanaa," Ali Muse of Mogadishu Ambulance service said.

He adds, "The wounded, including some in serious conditions, were admitted in Daynile and Keysaney hospitals."

The clashes come just three days after more than 70 people killed and over 180 others injured in heavy clashes that rocked the restive seaside city.

Somalia has been without an effective central government since 1991 and, almost half of its population-- 3.8 million people--are in dire need of humanitarian food aid.
