At least two people were killed and five others wounded when unidentified men opened fire on worshippers exiting a church after the Sunday service in Quetta, media reports said on Sunday.
The bike-borne assailants on Sunday targeted the church in Essa Nagri area of the city, Express Tribune reported.
Two people were killed in the attack, police said, adding the injured have been hospitalised.
After the attack, the community members with dead bodies staged a protest demonstration and blocked roads disrupting traffic, alleging governmentâ€™s â€œfailureâ€ to end attacks on Christians, according to the report.
Meanwhile, Balochistan Home Minister Mir Sarfaraz Bugti condemned the attack and expressed sorrow over the loss of lives.
The minister also assured action against the culprits, it said.
The attack comes two weeks after four members of a Christian family were gunned down in Quetta a day after the community celebrated Easter on April 1.
In December last year, nine people were killed and over 40 injured in twin suicide bombings on another Church in Quetta.
