Somalia ? The government’s grip on the city of Mogadishu is far from stable.

Islamic gunmen attacked police in Somalia’s capital Sunday, leading to an hourlong battle that left two dead. Meanwhile, a Somali government spokesman warned that fighters from the deposed Council of Islamic Courts were regrouping as Ethiopia prepares to withdraw.

Islamic fighters “are coming back to Mogadishu,” said the spokesman, Abdirahman Dinari. “They’re destabilizing sections of the city. They’re killing innocent civilians. They’re attacking police stations.”

Sunday’s battle started after gunmen attacked police in northern Mogadishu. It was not immediately clear who the victims were.

Two police stations were hit a day earlier with machine guns and rocket-propelled grenades, wounding five people.

On Sunday, Ethiopian Prime Minister Meles Zenawi told The Associated Press he would pull a third of his troops out of Somalia within the next two days. Meles spoke on the eve of an African Union summit in Addis Ababa.
