Up to 6 armed militants storm police training academy and open fire. (AAP)  Islamic State says its fighters attacked a police training college in the southwestern Pakistani city of Quetta, in a raid that officials say killed 62 people and wounded more than 100.  "Fifty-nine people died in the police centre, in addition to the three attackers, and around 100 were injured," said Anwar-ul-Haq Kakar, government spokesperson for Baluchistan province.  Hundreds of trainees were stationed at the facility when masked gunmen stormed the college on the outskirts of Quetta late on Monday. Some cadets were taken hostage during the raid, which lasted nearly five hours. Most of the dead were cadets.  "Militants came directly into our barrack. They just barged in and started firing point blank. We started screaming and running around in the barrack," one police cadet who survived told media.  "I saw three men in camouflage whose faces were hidden carrying Kalashnikovs. They started firing and entered the dormitory but I managed to escape over a wall," another cadet said.  Dozens of people injured in the attack on police academy. (AAP)  Military operation launched to rescue hostages. (AAP)  Other cadets at the college spoke of jumping out of windows and cowering under beds as masked gunmen hunted them down.  Video footage from inside one of the barracks showed blackened walls and rows of charred beds.  Islamic State's Amaq news agency published the claim of responsibility, saying three IS fighters "used machine guns and grenades, then blew up their explosive vests in the crowd".  No militant group has claimed responsibility. (AAP)  But Pakistani officials earlier said another Sunni extremist group, Lashkar-e-Jhangvi, was probably behind the raid.  Mir Sarfaraz Bugti, home minister of the province of Baluchistan, whose capital is Quetta, said the gunmen attacked a dormitory in the training facility, while cadets rested and slept.  Pakistani troops backed by helicopters launched a major operation against the militants, rescuing hundreds of trapped cadets and killing two more attackers, officials said.  "Two terrorists killed and 200 [cadets]… rescued Alhamdo lillha (by God's grace)" Mr Bugti tweeted.  © Nine Digital Pty Ltd 2016
