At least 10 people were killed Sunday in Somalia's capital Mogadishu, as Islamist rebels and African peacekeepers exchanged artillery fire, Radio Garowe reports.
Most of the dead and wounded persons were families who recently returned to their Mogadishu homes after Ethiopian troops withdrew in January, locals said.
At least 18 wounded persons were being treated at medical centers, according Rufa Ahmed Salad, who works at Dayniile Hospital.
Al Shabaab Islamist hardliners claimed responsibility for mortar attacks targeting the main port in Mogadishu, with witnesses saying African Union peacekeepers (AMISOM) responded to the attack with the heavy barrage of artillery fire.
Somali government officials rejected the opposition's allegations that a ship unloaded military hardware for AMISOM peacekeepers.
Located in the Horn of Africa region, Somalia has been mired in armed conflict since the early 1990s and more than a dozen attempts at restoring national order have failed.
