QUETTA -- At least four people were killed and seven injured Sunday (March 17) when a remote-controlled bomb exploded on a railway line in Balochistan province as a passenger train was passing by, police said.
The incident occurred 311km southeast of Quetta.
"The train was going from Quetta to Rawalpindi when it came over a remote-controlled bomb and four people were killed while seven others were injured," senior police official Irfan Bashir told AFP.
"Three carriages of the train also went off the track, and rescue work is under way," he said.
The incident was confirmed by another senior police official, Rao Munir Zia.
No group has claimed responsibility for the attack, but Baloch separatist groups and Islamist militants regularly attack railways in the province.
