The United Nations (UN), via spokesman Stephane Dujarric, is “concerned” about personnel aboard a helicopter flying under the world body’s flag after it was reportedly seized by al Shabaab militants in Somalia. Local sources told the BBC that al Shabaab had seized the helicopter along with eight passengers and crew. A UN memo on the incident seen by Agence France Presse said the helicopter crash-landed about 70 km southeast of Dhusamareb and no United Nations staff were on board as the helicopter was crewed by contract personnel.
