Somali government troops backed by African Union peacekeepers killed 40 insurgents on Sunday in clashes in north Mogadishu, the government said. "We have killed 40 fighters from al Shabaab group and we continue to repulse them. We have now pushed them back from three northern districts of Mogadishu. AU peacekeepers were assisting us," said Salad Ali Jelle, a parliamentarian who was involved in Sunday's fighting, according to a report of Reuters.
