Lebanese officials say a series of suicide bomb attacks on a cafe in the northern city of Tripoli have left at least nine dead and 37 wounded. Witnesses say two bombers set off explosives at a cafe located in a predominantly Alawite neighborhood in Lebanon's second-largest city. Authorities identified the attackers as residents of the nearby Sunni Mankubeen district. The al-Qaida-linked Nusra Front has claimed responsibility for Saturday's attack.
