Terrified revellers at a gay bar in Oslo hid in a basement and desperately called loved ones as a gunman went on the rampage, killing two people and injuring 21 on the day the city was due to celebrate its annual Pride parade. Authorities said the suspect, a 42-year-old Norwegian citizen of Iranian origin, was believed to be a radicalised Islamist with a history of mental illness who had been known to intelligence services since 2015. The suspect will be subjected to a psychiatric evaluation in the coming days as part of the investigation, police said. The attack took place in the early hours of Saturday, with victims shot inside and outside the London Pub, a longstanding hub of Oslo’s LGBTQ scene, as well as in the surrounding streets and at one other bar in the centre of the Norwegian capital. The deceased were two men in their 50s and 60s, police said.
