MOGADISHU (Reuters) - At least three Somali security personnel were killed when a car bomb targeting a United Nations convoy exploded near the airport in the Somali capital, police said.

There was no immediate claim of responsibility but in the past similar attacks against the U.N. have been carried out by al Shabaab militants who are allied with al Qaeda and want to topple the Western-backed government in Mogadishu.
