Heavily armed Al-Shabaab militants stormed an African Union (AU) base in Somalia on Tuesday, triggering a fierce firefight that left an unknown number of casualties, a local military commander and witnesses said.
AU forces dispatched helicopter gunships after the pre-dawn car bomb and gun attack on a camp housing Burundian peacekeepers near Ceel Baraf, a village about 160 kilometres (100 miles) northeast of the capital Mogadishu, the sources said.
