A series of bomb and gun attacks targeting police stations, mosques and churches left 63 people dead in northeastern Nigeria, a Red Cross official said Saturday. Attackers left scores injured -- probably more than 100 -- in the three-hour rampage in the Yobe state city of Damaturu, according to Ibrahim Bulama of the Red Cross. "It is a very bad scene," he said. Gunmen first attacked the police headquarters and the anti-terror office before moving to churches and mosques, he said. Most of the casualties are police officers. The attack came the same day suicide bombers suspected to belong to a militant Islamist group targeted a military base in nearby Maiduguri. Three suicide bombers drove a stolen black SUV toward a Joint Task Force headquarters, but could not get through the gate, military spokesman Lt. Col. Hassan Mohammed said. The blast damaged roofs and walls of the base.
