Local sources said a massive blast was heard in the Bulomarer district, around 150 kilometres (93 miles) south of Mogadishu, and fighting broke out after dozens of heavily armed Shabaab militants stormed the base. “The heavy blast struck the base before fighting broke out. We are hearing the militants used a minibus loaded with explosives to make their way in before the heavily armed confrontation started at the camp,” said local security official Ibrahim Abdilahi. “There was heavy fighting and we could see smoke rising above the military base,” said witness Mohamed Sharif. Ugandan army spokesman Brigadier Richard Karemire said UPDF had “lost four gallant soldiers and six sustained minor injuries”.
