QUETTA, Pakistan (AP) — A government official says 33 police trainees were killed when gunmen attacked a hostel at a police training center in Pakistan's restive southwestern Baluchistan province.

Baluchistan's top health official, Noor Haq Baloch, said at least 106 people were wounded — mostly police trainees and some paramilitary troops.

Hag said many of the trainees died when the gunmen detonated explosive vests.

Home minister Sarfaraz Bugti said one of the attackers was killed by security forces and two detonated their explosive vests. He said security forces have completed their operation but are still engaged in the cleanup process.

Major Gen Sher Afgan, chief of the paramilitary Frontier Corps, told reporters that the attackers appeared to be in contact with handlers in Afghanistan.
