Pakistan train bombings kill at least four

At least four people have been killed after two bombs went off in a train in western Pakistan.

Two bombs targeting a train in the restive western Pakistani province of Baluchistan have killed at least four people and wounded 16.

The bombs hit the Jaffer Express which runs between the provincial capital, Quetta, and Rawalpindi, next to the capital, Islamabad, said Kashif Akhtar, a senior railways official in Quetta.

"The train was stopped, and then as people were leaving the train, there was another explosion under a different (carriage)," he said.

No group has claimed responsibility for the explosions near the town of Mach, about 65 km southeast of Quetta. Ethnic Baluch rebel forces have targeted transport infrastructure in the province in the past.

Railways Minister Khwaja Saad Rafique, addressing reporters outside parliament in Islamabad, confirmed the attack.

Railway services from Quetta had been suspended and rescue services were tending to the wounded, Akhtar said.

Security forces foiled a similar attack on Thursday as an attacker laid explosives on a railway track near Quetta, he said.
