Quetta: At least seven people have been killed and six others injured in a passenger wagon bomb blast in Saturday morning.

Officials have confirmed that the wagon was traveling from Dear Bugti to Sui when it was blown by a remote controlled bomb in the Mail Bazar area.

Security officials have cordoned off the area the dead bodies and injuries are carried to the nearest hospitals.

So far none of the anti-government elements have claimed the responsibility but observers think that the incident does not any clear link to the deadly suicide attacks on former premier Benazir Bhutto’s Caravan of Democracy that killed up to 140 and injured nearly 500.
