A suicide bomber and gunmen stormed a hotel in Somalia's capital on Tuesday, killing at least 15 people including members of parliament in an attack that set off an hour-long gun battle, a military spokesman and a witness said. A parliamentarian who was at the Muna hotel said there were "dead bodies all over" and he labeled the scene a massacre. The assault comes after Somalia's most dangerous militant group, al-Shabab, declared a "massive war" on "invaders" an apparent reference to the 6,000 troops from the African Union that protect the weak Somali government.
