At least two people have been killed in revenge attacks after a car bombing at a Catholic church in northern Nigeria.
Anger erupted after a suicide bomber drove a jeep laden with explosives into the packed St Rita's building, killing eight and injuring more than 100.
One of the church's walls was blasted open following the attack in Kaduna, a city on the dividing line between Nigeria's largely Christian south and Muslim north.
"The heavy explosion also damaged so many buildings around the area," said survivor Linus Lighthouse.
Shortly after the blast in the Malali part of the city, angry Christian youths took to the streets armed with sticks and knives.
A Reuters reporter saw two bodies at the roadside lying in pools of blood.
"We killed them and we'll do more," shouted a youth, with blood on his shirt, before police chased him and others away.
Police set up roadblocks and patrols in an attempt to prevent the violence spreading.
There was no immediate claim of responsibility for the jeep bombing.
But Islamist sect Boko Haram has claimed similar attacks in the past and has attacked several churches with bombs and guns as it intensified its campaign against Christians in the past year.
At least 2,800 people have died in fighting since Boko Haram's campaign began in 2009, according to Human Rights Watch.
Most were Muslims in the northeast of the country, where the sect usually attacks politicians and security forces.
