Attackers on a motorcycle open fired on Christians in Pakistan as the worshipers were coming out of a church near Quetta, Dawn reported.
At least two people were killed and five other wounded in the attack in the Essa Nagri area on April 15.
The shooters fled the scene and were not apprehended.
The attack follows another horrific shooting this month in the area in which four members of a Christian family from Punjab travelling in a rickshaw to visit relative were all gunned down.
In December 2017, suicide bombers attacked the Bethel Memorial Methodist Church, also in Quetta, killing nine and injuring 30.
