Unidentified gunmen shot dead a Christian priest and wounded another as the clerics drove home from church in Pakistan"s northwestern city of Peshawar on Sunday, police said. Two attackers on a motorcycle opened fire on the car on the city"s ring-road, killing Pastor William Siraj instantly, officers added. No one immediately claimed responsibility for the shooting in a city where scores of people died in a twin suicide bombing outside a church in 2013. Azad Marshall, the most senior bishop in the Church of Pakistan, condemned the attack and tweeted: "We demand justice and protection of Christians from the Government of Pakistan." Pakistan"s northwestern areas bordering Afghanistan have seen a rise in militant attacks on security forces in recent days, many of them claimed by Tehreek-e-Taliban Pakistan (TTP), a group which associates itself with the Afghan Taliban. TV footage showed emergency services removing Siraj from the car, and people carrying his body on a bed through the streets to a house. Mourners hugged each other and sobbed. Pastor Siraj"s colleague -- named by Bishop Azad as the Reverend Patrick Naeem -- was out of danger and being treated for his injuries, a spokesman for the city"s Lady Reading hospital said. Bishop Azad said both were clergy of the Diocese of Peshawar in the Church of Pakistan, which is a union of protestant churches including the Methodists and the Anglicans. — Agencies
