At least 17 people were killed in the Somali capital of Mogadishu when five Islamist gunmen set off bombs and stormed a popular beach-front restaurant late on Thursday, Somali police said. Al Shabaab, a militant group aligned with al Qaeda, said its fighters set off two car bombs at the Beach View Cafe on Mogadishu's popular Lido beach, and engaged in a gun battle for hours with government troops trying to flush them out. Somalia's security minister, Abdirizak Omar Mohamed, said four of the gunmen were killed and one was captured alive.
