Four Christians were shot dead in southwestern Pakistan on April 2, police said, in an attack claimed by the Islamic State militant group.
The group was travelling in a rickshaw when armed men on a motorcycle intercepted them and opened fire in Quetta city, the capital of Balochistan province.
Three members of a family and the rickshaw driver were immediately killed, but a fifth -- a child -- survived and was rushed to the hospital, police said.
"It appears to have been a targeted attack," provincial police official Moazzam Jah Ansari told Reuters. "It was an act of terrorism."
The attack came a day after Pakistan's Christian community celebrated Easter. Around 2 percent of Pakistan's 200 million people are Christians.
