SINGAPORE, Nov 26 (Reuters) - Singapore has ordered

TikTok and Meta to block access in Singapore to the accounts of

an Australian man authorities say has contributed to the

radicalisation of two of its citizens, the ministry of home

affairs said on Tuesday.

Former Singaporean Zulfikar bin Mohamad Shariff "called on

Muslims to reject the constitutional, secular, democratic state

in favour of an Islamic state governed by Syariah law", said the

ministry in a press release.

"He believed that violence should be used to achieve this

goal if necessary."

Zulfikar was detained in 2016 under Singapore's Internal

Security Act for promoting terrorism and the online

glorification of the Islamic State.

The 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.

Authorities said Zulfikar "repeatedly continued to stir up

discontent within the local Malay/Muslim community against the

Chinese community in Singapore".

They cited a Tiktok video posted in June in which Zulfikar

said that Malays and Muslims had been forced to move away from

Islam and assimilate into the Chinese community.

Zulfikar, who renounced his Singaporean citizenship in 2020,

was also accused of trying to interfere with this year's

election in the city state.

In multiracial Singapore, 74% of the resident population are

Chinese, 13.6% are Malay, 9% Indian and 3.3% classified as

others. The city-state is also a melting pot of various

religions.

"The Singapore government takes a very serious view of

threats to our racial and religious harmony, including from

foreigners, and will not hesitate to act against them," said the

ministry.

The government issued the directions to TikTok and Meta

under the Online Criminal Harms Act, which came into force in

February 2024.

TikTok and Meta did not immediately respond to a request for

comment.
