Worshipers were celebrating the 30th anniversary of their Salvation Army church when a group of Muslim youths gathered outside the building and harassed women as they arrived.
After two men asked the youths to stop teasing the women, the youths left, then returned with handguns. An argument erupted into gunfire, killing two men instantly and wounding two others. Congregation members complained that local police refused to register the case until they protested and blocked a main road with the bodies of the dead men.
The killings came a week after another Christian, sentenced to life imprisonment on blasphemy charges, died in Karachi Central Prison. The family of Qamar David claims he was murdered on March 15, while authorities claim he died of heart failure.
On March 2, Federal Minister for (religious) Minority Affairs Shahbaz Bhatti was assassinated in Islamabad after he opposed the laws that make criticism of the Prophet Muhammad punishable by death.
