“There is a ceasefire, but we don’t know exactly what will happen after this,” he told the media on the sidelines of a community event on Saturday, The Straits Times (ST) reported.

He noted the possibility of attacks on both sides.

Shanmugam said that individuals or extremist organisations might want to make a point against Israeli, American or other Western assets. There could also be attacks from the far right on Muslim assets.

“So we have increased our security posture, working off different scenarios, but you know, you can never be absolutely sure.”

However, when asked whether there had been an uptick in suspicious or extremist activities following the recent US air strikes on Iranian nuclear facilities, he said authorities had not detected anything here yet.

“But they need to succeed only once,” he said.
