Mogadishu — Heavy fighting reportedly broke out Friday between Somali government soldiers and Al shabab fighters in rebel-held locations outside Baidoa, the third largest city in southern Somalia.

Official in Bay region say the battle sparked when government forces attacked bases controlled by Al shabab militants and the attacks lasted last night until on Friday morning.

"We could hear deafening sounds of mortar and artillery shelling used by the warring sides in Goofgaduud area located around Baidoa this morning. The fighting is between Somali forces and Al shabab. I can't confirm the exact casualties on either rival sides or civilians," said a resident in Goofgadud, who asked to be named for security reasons.

The situation is said to be calm after the combat stopped Friday noon, but the locals say the fighting could restart any time in the area since both sides stationed close positions and receiving reinforcement.
