At least six people, including three civilians, have been killed in Somalia’s northern Puntland region after a roadside bomb exploded as security forces tried to defuse it.
The Wednesday blast occurred in Galkayo, a town separating the semi-autonomous Puntland from the self-proclaimed separate region of Galmudug.
"Three members of the security forces and three civilians were killed in the explosion," security official Mahdi Abdulahi said.
No group has claimed responsibility for the blast, which is the latest in a series of attacks in the restive region controlled by various militia forces.
Somalia has not had a functioning government since 1991, when warlords overthrew former dictator Mohamed Siad Barre.
The weak Western-backed transition government in Mogadishu has been battling the al-Shabab fighters for the past five years, and is propped up by a 12,000-strong African Union force from Uganda, Burundi and Djibouti.
Somalia is one of the countries generating the highest number of refugees and internally displaced people in the world.
