Most terrorist-related books are owned by individuals - Nur Jazlan

"Definitely, they (books) can be banned but what is normally banned is public distribution, if the book is not distributed to the public, KDN need not take action. Distribution is normally via publication and sold in shops. But if the book is individually owned, it need not necessarily be banned so it is still being considered for banning as it is still not distributed to the public," he said when commenting on the five-year jail for Siti Noor Aishan Atam who was found guilty on a charge of possessing 12 books promoting militant ideologies like IS.

Siti Aishah, who was first detained in March 2016, was found guilty under Section 130JB of the Penal Code and Security Offences (Special Measures) Act 2012 (SOSMA).

He was met after the simultaneous opening of the ''Malaysiaku Negaraku'' and ''#BlackoutBumiSakit: Besama Selebriti Selamatkan Dunia'' programmes at Comedy Planet on Thursday.

Meanwhile, Nur Jazlan warned non-government organisations (NGO) to cease issuing statements which could cause racial tensions, adding that KDN was monitoring the action of certain groups which were seen trying to raise racial issues and religious hatred.

"I urge these groups to stop their public verbal spats, whether Islamic or Hindu groups. Stop it. KDN is monitoring this to determine if the public verbal exchanges can threaten public order. But, to date, it has not reached a volatile stage. We want them to stop it as it will not benefit anyone," he said.

On Wednesday, 22 Malay NGO urged the government to ban the Hindu Rights Action Force (Hindraf) which it regarded as racist, extremist and threatening national security.

One of the NGO, Barisan Bertindak Melayu Islam (Bertindak) also regarded Hindraf as an uncouth organisation and could bring catastrophe and ruin the inter-racial ties.
