MAIDUGURI, Nigeria (AP) — 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 Islamic extremists step up attacks and criticism mounts of the failure of the military and government to suppress the 4-year-old Islamic uprising in the northeast.
