(AP Photo/AAP Image, Julian Smith) (Newser) – Australian police shot and killed a terror suspect after he stabbed two officers yesterday, officials say. The suspect has been identified as Numan Haider, an 18-year-old Australian whose passport had been canceled amid terror concerns, the AP reports. Officers were concerned he was planning to behead police, cover their bodies in a flag, then post pictures online, following ISIS instructions, the Sydney Morning Herald reports. Police asked him to come to a station in Melbourne for questioning after he'd been on their radar for three months; he'd recently been reported displaying an ISIS flag at a shopping center. Officers met him outside the building at his request, Australia's ABC News reports; when one tried to shake his hand, he stabbed the officer, police say. Both officers are in stable condition. A search of Haider revealed another knife, as well as an ISIS flag, the Morning Herald notes. Haider's family, from Afghanistan, had recently been worried about his behavior, a family friend tells ABC. He had been linked to a radical Melbourne-based group known as al-Furqan that has previously been raided by police, but he had reportedly drifted from the group.
