Heavily armed Al-Shabaab jihadist fighters on Tuesday attacked a military base in Somalia where African Union peacekeepers are stationed, causing casualties, a local military commander and witnesses said. The AFP news agency reports that the pre-dawn raid targeted a camp housing Burundian troops near Ceel Baraf village about 160 kilometres northeast of the capital Mogadishu, but there was no immediate comment from the African Union’s mission in Somalia.
