Several mortar shells landed at the heavily fortified Halane base camp which houses AU forces headquarters in Mogadishu Wednesday evening.
A source within the facility told the shelling hit the facility and that there were a number of casualties.
The militant group Al-Shabaab claimed responsibility noting it fired five mortar shells.
Today’s attacks come barely barely two weeks after a similar one in March 1.
A foreign national was reportedly injured in the attack.
