alongside Islamic State militants, authorities said on Wednesday. The 17-year-old male was detained and subscribed to far-right extremist ideology, seeing himself as an "East Asian supremacist," authorities said. He wanted to shoot mosques and had unsuccessfully tried to buy guns, including from the United States, Malaysia and Thailand, the internal security department said.

The teenager wanted to "maximize casualties" and kill at least 100 Muslims, to outdo the 2019 Christchurch attack in which a gunman killed 51 worshippers in a mosque, it said. Detained in March under the island's Internal Security Act, he could be held for up to two years without trial. He was identified following an investigation into an 18-year-old detained in December over similar far-right extremism, authorities said. Authorities said they were concerned about youth radicalization in Singapore, and have used the Internal Security Act against 17 youth aged 20 and under since 2015. That law allows suspects to be held for lengthy periods without trial, or to be given a restriction order limiting travel and internet access, among other conditions. (Reuters)
