Blast in the vicinity of airport in Somali capital - witnesses
A security adviser, based at the airport, told Reuters by telephone there had been a suspected VBIED, or vehicle-borne improvised explosive device, in the area, without giving further details. The Somali Islamist group al Shabaab has often used car bombs but there was no immediate claim of responsibility.
