A large blast has been heard in an area near the airport in the Somali capital of Mogadishu, just hours after a series of explosions at law courts in the capital and gunmen stormed the building, residents said.
"We heard a blast ... and then soldiers opened fire. I see only thick smoke rising into the sky. I do not know what caused the blast. The whole area has been immediately besieged by security forces," one resident, Halima Osman, told Reuters.
