Pakistan's counter-terrorism units have raided a hideout of the Islamic State group in the restive southwestern Baluchistan province before dawn, setting off a shoot-out that killed 11 militants, police say.
The units, acting on intelligence, carried out the raid in the district of Mastung, where IS militants had recently killed two police officers.
The police said suicide belts, hand grenades and assault rifles were confiscated in the raid.
The counter-terrorism department provided no further details and the nationality of the slain militants was not immediately known. The counter-terrorism police is a special branch of the police that fights militant groups.
Quetta is the capital of Baluchistan province where the IS group has claimed several attacks in recent years. IS has regional affiliates in both Pakistan and neighbouring Afghanistan.
Baluchistan is also the scene of a low-level insurgency by Baluch separatist groups, which have also targeted non-Baluch labourers. However, unlike IS, they have no history of attacks on the minority Shi'ite community.
