gun have opened fire on a vehicle in the Pakistani city of Quetta, the capital of the southwestern Balochistan Province, killing four Shia Muslims, police say.
The shooting took place in the Masjid Road area of Quetta on Monday, AFP reported.
According to Fayyaz Sumbal, a senior police official in Quetta, all the four victims were Shias. He added that the assailants fled the scene after the shooting.
Another police official in Quetta, Rahim Khan, also confirmed the incident, saying that the gunmen riding in a car shot the victims travelling in a different vehicle.
No group has yet claimed responsibility for the attack but the outlawed Pakistani terrorist group Lashkar-e-Jhangvi has often been behind a series of deadly attacks on Shia Muslims.
In recent months, violence has escalated against Shia Muslims in different parts of Pakistan.
According to Human Rights Watch, more than 400 Shias were killed in Pakistan in 2012, which was the deadliest year on record for the Shia Muslim community.
Shias make up about a third of Pakistan’s population of over 180 million.
