Sydney (AFP) - Five people, including a 15-year-old boy, were charged Thursday in Sydney over a terror plot targeting a government building, with authorities expressing alarm at the age of those being radicalised.

The teenager and a 20-year-old man were seized at their homes Thursday morning and accused of conspiracy to conduct an act in preparation for a terrorist act. Three others currently in jail, aged 21, 22, and 22, were later charged with the same offence, police said.
