MAIDUGURI, Nigeria — Twin car bombs at a bustling city marketplace blasted buildings to rubble and tore apart bodies the same night an attack on a farming village razed every thatched-roof hut. At least 90 people have been killed, officials and survivors reported Sunday, as Nigeria's militants step up attacks and criticism mounts of the failure of the military and government to suppress the 4-year-old uprising in the northeast. In Maiduguri, capital of Borno state and birthplace of the Boko Haram militant network, the attackers chose a densely populated area with narrow alleyways that maximized the blasts and a Saturday night when the market was open late. The victims include children dancing at a wedding celebration and people watching a soccer match at a cinema, survivors told The Associated Press. Fifty-one bodies were retrieved by Sunday morning but many more are believed buried in rubble, said a Red Cross official. In Maiduguri, the first bomb came from a pickup truck loaded with firewood, said Hassan Ali, the leader of an anti-terror vigilante group. Many more people were killed in the second blast, which was timed to catch people who rushed to the aid of those wounded in the first explosion, survivors said. — AP
