Abuja , Nigeria ( CNN ) -- Three church bombings and retaliatory attacks in northern Nigeria killed at least 50 people Sunday and injured more than 130 others , the Nigerian Red Cross Society said . The series of attacks began when a suicide bomber drove at high speed through a barricade at the EWCA Goodnews Wusasa Zaria church around 9 a.m. , congregation member Lucy Bello said . That blast left at least 24 people dead and 125 injured , some in critical condition , according to a Kaduna state government official who asked to remain anonymous because he was not authorized to speak to the media . The Nigerian Red Cross Society , however , reported that two people were killed and 22 injured in the attack . Bello , who had bruises from the explosion , said the dead and wounded were thrown to the ground by the blast . Within minutes , another explosion occurred at the Christ the King Catholic Church in Zaria , according to the National Emergency Management Agency . At least 10 people were killed in that attack and more than 50 were injured , the state government official said . Again , the Nigerian Red Cross Society offered a conflicting report , saying that 16 people were killed and 31 injured in that attack . Later , at least 10 people were killed in a bombing at a church in the city of Kaduna , Red Cross spokesman Andronicus Adeyemo said . Christian youths in Zaria and Kaduna reacted violently , burning tires and blocking major roads . The Kaduna state government imposed a 24-hour curfew . Thirty-two people were killed and 78 injured in the third blast , including victims of the reprisal attacks , the Nigerian Red Cross Society said . The bombings are the latest in a string of violence directed at churches . A week ago , a car bomb killed five people during services at a church in Jos , also in northern Nigeria . Angry crowds wielding makeshift clubs fought with police after chasing security forces away from the destroyed church . Three more people died in the clashes . And two weeks ago , two church bombings in the region killed at least 15 people . No one immediately took responsibility for Sunday 's attacks , though Nigerian President Goodluck Jonathan suggested they were the work of Boko Haram , a militant Islamist group . `` We will not let Boko Haram intimidate our Christian community or police officers . We will fight these terrorists until there are none left , '' he wrote on Twitter page Sunday . Boko Haram has previously carried out attacks , including at churches . The group also refers to itself as the `` Nigerian Taliban '' and seeks to overthrow the government and replace it with a regime based on Islamic law . `` Boko Haram '' means `` Western education is forbidden . '' CNN 's Vladimir Duthiers and Nana Karikari-apau and journalist Safiya Akau contributed to this report .
