Gunmen have killed one Christian priest and wounded another as they were driving home from Sunday Mass in Pakistan’s north-western city of Peshawar, police said.

Father William Siraj, 75, was shot multiple times and died instantly in the ambush in the Gulbahar neighbourhood, while Father Naeem Patrick was treated briefly in hospital for a gunshot wound to the hand, officer Iqbal Shah said.

A third priest in the car was unharmed.

No-one immediately claimed responsibility for the attack, the latest on Pakistan’s tiny Christian minority that has been targeted several times by militants in recent years.

Militant violence has seen a broader increase since the Pakistani Taliban ended a ceasefire with the government last month.

A memorial service for Father Siraj will be held on Monday at Peshawar’s All Saint’s Church, which was brutally attacked by militants with bombs and gunfire in 2013.

More than 70 worshippers were killed and 100 wounded.

Police said they were reviewing CCTV footage to locate the attackers, who witnesses said escaped on motorcycles.

Chief minister Mahmood Shah of Khyber Pakhtunkhwa province condemned the attack, urging police to find the culprits as soon as possible.

Bishop Humphrey Peter also condemned the killing, saying it aimed to harm interfaith harmony.
