Somalia: Four killed in Mogadishu suicide bombing
Sources say, national intelligence officers in armored vehicles were targeted in the coordinated terror attack.
A spokesman for Al Qaeda linked Al Shabaab militants said, they are responsible for the attack on US-trained military personnel.
The attacked convoy was racing through a heavily militarized road that leads to Adan Adde International airport.
Somalia-based Islamist insurgents lost a string of strategic towns in central and southern Somalia to intense onslaught by Somali government forces and African Union peacekeepers.
