Pakistan's Christian leaders said they have closed their schools and colleges across the Muslim-majority country for three days to mourn and protest the killings of eight of their religious brethren.
Hundreds of Muslims stormed a Christian neighbourhood in Gojra city on Saturday, burning dozens of houses.
Six Christians were burned to death and two died of gunshots.
The violence was prompted by allegations that some Christians had desecrated a Quran.
Bishop Sadiq Daniel says the Christians' want to register their anger and concern peacefully. He on Monday said that the government must "bring all perpetrators of the crime to justice."
A spokesman for Pakistan's president said a judicial panel will probe the incident.
