At least one police officer has been killed and five more wounded as a suicide bomber targeted a paramilitary convoy in southwestern Pakistan.

Authorities recovered the remains of a female bomber following the explosion in the southwestern city of Turbat, said Bashir Ahmed, a top administrative officer.

Jeeyand Baloch, spokesman for the separatist Baluch Liberation Army, later claimed responsibility for the attack.

Ahmed said the bomber had targeted a convoy of the paramilitary Frontier Corps but the main thrust of the blast hit a police vehicle. He said a Frontier Corps vehicle was slightly damaged and a female police officer was among the wounded.

Southwestern Baluchistan province has been the scene of a low-level insurgency by Baluch separatists.
