QUETTA: An improvised explosive device (IED) blast killed two policemen and wounded six others in a roadside attack in the Spini road area of the provincial capital on Tuesday evening, police said.

A police contingent patrolling the area was targeted with an IED, police official said.

"Four police officials and three passers-by were injured in the blast, which also damaged the police vehicle."

The injured were taken to Civil Hospital Quetta, where two police officials succumbed to their injuries and were pronounced dead.

There was no immediate claim of responsibility for the attack which comes a week after a similar attack in city's eastern Bypass area which left one policeman dead and seven others injured.

Interior Minister Balochistan Mir Sarfraz Bugti visited the site of the incident and condemned the 'act of terrorism' by enemies of the state.

Balochistan, Pakistan’s largest but least developed province, has remained under the grip of violence for over a decade which has claimed thousands of lives.
