Ethiopian troops allied to Somalia's government shot dead 13 civilians after an explosion killed two soldiers Wednesday, witnesses in southwestern Somalia said. Witness Mohamud Ahmed Nur said what appeared to be a remote-controlled land mine hit the Ethiopian troops patrolling Baidoa town and killed two soldiers. The soldiers, he said, then opened fire in all directions, killing at least 10 civilians who were passing by, according to a report of the Associated Press. Mohamed Hussein Diriye, a doctor at the town's main hospital, said three other people died later of their injuries while being treated at his facility. Seven other wounded were being treated at the hospital, he said.
