It happened this morning in Pakistan. From The New York Times:
Two suicide bombers attacked a church packed with worshipers on Sunday in southwestern Pakistan, killing at least eight people and injuring at least 30 others, several critically, officials said.
The Islamic State, also known as ISIS, claimed responsibility for the attack in Quetta, the capital of the restive Baluchistan Province, in the country’s southwest. The group’s Amaq News Agency posted a statement online Sunday that said attackers had stormed a church in Quetta, but gave no further details.
The assault raised concerns about the security of religious minorities, especially Christians, in a country with a dismal record when it comes to the treatment and protection of religious minorities, analysts say.
Pakistani officials denied that ISIS had an organized presence in the country, however, even though the terrorist group has claimed responsibility for several other attacks in Baluchistan in recent years.
…The attack, a week before the Christmas holiday, unfolded in the early morning hours at Bethel Memorial Methodist Church. About 400 people had gathered for Sunday service when an assailant detonated his explosives-laden vest near the door to the church’s main hall.
Another attacker failed to detonate his suicide jacket and was shot by security forces after an intense firefight, officials said.
Sarfraz Bugti, the provincial home minister, said the death toll could have been higher had the attacker managed to reach the main hall of the church, which is on one of the busiest roads in the city and near several important public buildings.
Local television networks broadcast images of terrified worshipers running out of the church as the attack was underway. Several young girls, wearing white frocks and holding red bags, could be seen fleeing the compound. Witnesses told local news outlets that people, panicked and frightened, had rushed out after hearing a loud explosion, followed by the sound of gunfire outside.
