Beyond counter-terror drills, people have a vital role to play

I read with concern that two more self-radicalised individuals were detained by the Internal Security Department (ISD detains Singaporean teen who wanted to kill at least 100 Muslims at 5 mosques; and S'porean girl, 15, who wanted to marry ISIS fighter, is first female teen dealt with under ISA, both April 2).

The threat of terrorist attacks caused by self-radicalisation is a reminder that even if racial and religious relations in Singapore are healthy, a handful of isolated followers from extremist and sectarian movements can have an outsized impact if they succeed in their attacks.

Extremist and sectarian forces could seek to fan the flames further and divide our country. Some troublemakers could even be well-funded state-sponsored actors.
