Bombs rocked three churches in neighbouring cities in Nigeria’s northern Kaduna state on Sunday, injuring dozens of worshippers, emergency services and residents said. The number of casualties in the blasts in the neighbouring cities of Zaria and Kaduna was not immediately clear. Police and the military cordoned off the areas around the churches. The state-run National Emergency Management Agency (NEMA) said the blasts happened in the Wusasa and Sabongari districts of Zaria, previously targeted by the Islamist group Boko Haram. Residents in the areas said many people were injured in the attacks on the Christ the King Catholic Cathedral and ECWA GoodNews Church. “Many people in the church were injured but I have not seen any dead bodies,” a woman who was in the church in Wusasa at the time of the explosion said by telephone from her hospital bed. Several residents in Sabongari said the church was badly damaged. “I went close to the church but could not access it due to heavy police and military security deployed around it,” resident Mahmud Hamza told AFP.
