At least six policemen were killed and 13 wounded today in five blasts at a police training school in Pakistan's southwest, police said.
The explosions occurred in the firing range of the police training school on the outskirts of Quetta, capital of the restive Baluchistan province.
There was confusion over the nature of the explosive devices, with some police saying they were remote-controlled bombs, while others said landmines caused the blasts.
A hospital official said six bodies and 13 wounded had been received at the hospital.
The bombs went off in quick succession when commandos of the police Anti-Terrorist Force were training.
No one has claimed responsibility for the blasts, but police blamed the Baluch Liberation Army, a militant group listed as a terrorist organisation by the government last month.
