A suspected mortar attack targeted the offices of United Nations and African Union peacekeeping mission in the Somali capital Mogadishu on Tuesday.
The offices are located inside the heavily-protected Adan Adde International Airport and the compound houses several western diplomatic missions in Somalia.
Security sources told Anadolu Agency by phone that at least three explosions hit the compound.
However, eyewitnesses at the airport told Anadolu Agency by phone they heard over five explosions in and around the airport.
There are still no reports of casualties as investigation is underway.
Somali-based terror group al-Shabaab has claimed responsibility for the attack. The group had targeted the UN compound several times in the recent past.
