AKIPRESS.COM - A Briton and a Frenchman working for the United Nations were shot dead on Monday at an airport in north-central Somalia, Reuters report Monday citing officials.

UN mission spokesman said it was not clear who was behind the killings, but one witness said the pair were attacked by a man in a police uniform while they sat in their car at Galkayo airport.

Abdi Idris, an official in the semi-autonomous Puntland region which administers the airport, gave the nationalities of the two men and said they worked as consultants for the U.N. anti-drugs agency.

The United Nations has often been targeted by warring clan factions, most recently by al Qaeda-aligned Islamist group al Shabaab.

UN Secretary-General Ban Ki-moon and the UN Security Council both strongly condemned the attack on Monday and called on Somali authorities to bring the perpetrators to justice.
