A Somali soldier and four militants were killed Sunday as an al-Qaida-linked extremist group tried to attack a training compound used for intelligence officials in Mogadishu, AP quoted a police officer as saying. The attack started with a suicide car bombing outside the intelligence school, which killed two attackers and a soldier, police Capt. Mohamed Hussein said Sunday. He said soldiers then shot two gunmen who had seemingly lost their way and stormed a civilian house close to their target. The al-Qaida-linked al-Shabab group claimed responsibility for the attack.
