Islamabad, Aug 16 (EFE).- Four people were killed and a score of others wounded Friday in an attack on a passenger train in western Pakistan, police told Efe.
"First they launched a rocket that damaged the train engine, but did not cause casualties, and later a firefight broke out between the attackers and the security forces who arrived at the scene," Ghulam Murtaza said from a police post in the Bolan district.
While unable to identify the dead, the officer said all of the wounded were train passengers and that four of them were in critical condition.
No group has claimed responsibility for the late morning attack on the Jaffar Express, which links the southwestern city of Quetta with Rawalpindi, near Islamabad.
The assault took place in Dozan, a municipality roughly 100 kilometers (60 miles) south of Quetta, capital of the impoverished, conflictive province of Baluchistan, which is plagued by violence from armed separatists, Islamist militants and organized crime.
Friday's incident comes less than two weeks after two people died and two-dozen others suffered injuries when a bomb went off on the Shalimar Express passenger train as it traveled south from Lahore to Karachi.
