Kano, Nigeria (CNN) -- A series of Boko Haram raids on four villages in northeast Nigeria's Borno state has killed more than 50 people and destroyed more than 300 structures, including five churches, a government official said. On Sunday, gunmen on motorcycles stormed the Christian villages of Kwada, Ngurojina, Karagau and Kautikari near Chibok, the scene of the April 14 abduction of more than 200 schoolgirls, opening fire on residents and hurling explosives into homes and churches. Kwada was the worst affected. There, the attackers razed the village and its five churches during the attacks, which lasted five hours. "We lost 54 people in the Sunday attacks on the four villages carried out by Boko Haram insurgents, who also destroyed over 300 homes," a senior Borno state government official said.
