The blast struck a police vehicle providing security at the Sacred Heart church in Baghdad`s central Karrada district, the source said.
Last October, 52 people died in an assault on a Syrian Catholic cathedral in central Baghdad. The attack was the bloodiest against Iraq`s Christian minority since the 2003 U.S.-led invasion.
Iraq`s Christians once numbered about 1.5 million but are now believed to have fallen to less than 850,000 out of a population of 30 million.
Hundreds of Christian families have fled to Iraq`s northern Kurdish region or to nearby countries since the October assault on the cathedral, the United Nations has reported.
Easter Sunday marks the resurrection of Christ after his crucifixion. (*)
