A blast targeting a passenger train killed four people including a woman and her daughter, and injured six others in Pakistan's restive Balochistan province on Sunday.
As the passenger train reached Dera Murad Jamali, there was a huge blast.
Officials said that four people were killed and eight sustained injuries as five coaches of the train derailed and were damaged in the blast.
The injured have been shifted to a nearby hospital for medical treatment.
No group has claimed responsibility of the attack in the restive province, where separatists accuse the government of unfairly exploiting the region's gas and mineral wealth.
Police and personnel of other law enforcement agencies reached the spot as investigation into the incident were under way.
