Residents of the Sabongari area in northern Nigerian city of Zaria watch billows of smoke from explosions at the Christ the King Catholic Cathedral following a suicide bomb attack during church service on Sunday.
KADUNA, Nigeria (AP) -- Aid workers in Nigeria have been searching for bodies among charred vehicles and destroyed market stalls after Sunday's trio of church bombings.
The Nigerian Red Cross says 50 people were killed in the bombings and reprisal attacks that followed.
A radical Islamist sect says it carried out the suicide attacks at two churches in the city of Zaria and another in the city of Kaduna.
The group known as Boko Haram has also claimed responsibility for similar attacks the previous two weekends. It's been blamed for more than 580 deaths this year, according to an AP count.
Churches have become frequent targets of attacks in the African nation which is almost equally divided between Muslims and Christians.
