@channelnewsasia: Three self-radicalised male Singaporean youths — aged 14, 15 and 19 — were detained under the Internal Security Act over the last three months, Minister for Home Affairs K Shanmugam said on Monday (Jul 27). While the cases were unrelated, Mr Shanmugam said all three had planned to conduct attacks in Singapore. Two of them planned to carry out attacks in their schools, with one being arrested just weeks before the planned event. #sgnews #singapore
