Mizanur Rahman, a convicted terrorist and former associate of Islamist radicaliser Anjem Choudary, has been using the social media platform TikTok to disseminate inflammatory messages targeting Britain, Israel, and the United States. Rahman, based in north London and released from prison in October 2018, has attracted nearly 2,000 followers and garnered close to 10,000 likes on his videos, despite his initial account being removed by TikTok moderators and subsequently reappearing under a new profile.

Rahman, 43, was previously imprisoned alongside Choudary in 2016 for inviting support for the Islamic State group. He was known for creating online chatrooms to facilitate communication among Choudary’s followers. His latest online activity includes videos in which he argues that most individuals convicted of terrorism offenses in Britain are not involved in violent acts but are instead punished for actions such as reading certain magazines or holding placards, notably those bearing the slogan “from the river to the sea.”

In addition to critiquing the UK’s counter-terrorism measures, Rahman has expressed strong anti-Western sentiments, describing Britain, the United States, and Israel as an “axis of evil” benefiting from perpetuating Islamophobia. He has also denounced Muslim police officers in the UK as “greedy sinners,” suggesting that financial motives cause some to compromise their principles.

Rahman’s history includes a 2007 conviction for soliciting murder, during which he openly called for British troops in Iraq to be killed, expressing a wish to see “their blood running in the streets of Baghdad.” His continued online preaching has raised concerns among anti-extremism experts who warn of the potential influence his messaging could have on vulnerable youth.

Professor Anthony Glees of the University of Buckingham highlighted the risks posed by such content on platforms popular with young users. He noted that last year nearly 1,000 young British Muslims were referred to the government’s Prevent counter-terrorism program, with 36 percent of these individuals aged between 11 and 15, an age group frequently engaged with apps like TikTok.

Rahman’s renewed online presence underscores ongoing challenges faced by authorities and social media companies in monitoring and countering extremist narratives that may contribute to radicalisation.
