Witnesses in southern Somalia say two Ethiopian soldiers and a civilian were killed in the latest attack by suspected Islamist insurgents.
They said gunmen shot the soldiers in a market in Baidoa Wednesday, prompting an exchange of fire in which a woman was killed.
On Tuesday, government forces and allied Ethiopian troops searched Mogadishu's sprawling Bakara market for weapons after fighting with insurgents late Monday killed at least six people.
Authorities consider the market a hotbed of insurgent activity.
Witnesses of Monday's fighting said at least four soldiers were among the dead. They also said insurgents temporarily took control of a major intersection and destroyed at least one government vehicle.
The insurgents have been fighting the government since Somali and Ethiopian troops drove an Islamist movement from power in Mogadishu in December 2006.
The fighting has killed thousands of Somalis and forced more than a half-million others to flee the capital.
