Somali militant group Al-shabaab have claimed responsibility for Thursday's attack on a military base used by Ethiopian troops in central Somalia. The militants claim to have killed 43 soldiers in the attack on Halgan. Halgan Town lies about 300 kilometers north of the capital, Mogadishu. The group says its fighters stormed into the base after ramming a suicide car bomb into the entrance. Residents said they heard a huge explosion at the base and a heavy exchange of gunfire shortly before dawn. The incident is the latest assault on soldiers serving with the African Union's AMISOM force.
