HATE preacher Anjem Choudary meets a Belgian terror group’s leaders — including one who is now the chief ISIS executioner in Syria.

A video Published recently shows Choudary shaking hands with extremists from the outlawed Sharia4Belgium, which has been linked to the ISIS cells behind the Paris and Brussels terror attacks.

One of them is Hicham Chaib, 32, who later fled Belgium to join ISIS and now heads its religious police.

He is in charge of beheadings, crucifixions and punishment amputations and has featured in an IS video shooting dead an alleged spy.

The Choudary film was shot as he made a morale-boosting visit to a handful of Islamic extremists in the Dutch city of Utrecht in late 2012.

Choudary, who is now facing ten years’ jail here after being convicted under the Terrorism Act, told them: “I come from England in order to radicalise the youth in this country.”

The audience was made up of members of Sharia4Belgium, which was directly funded by Choudary and also backed by his mentor, Omar Bakri Mohammed.

Bearded Chaib sat cross-legged in Muslim robes, and took detailed notes as Choudary spoke.

One Sharia4Belgium member later told Choudary’s aides: “Sometimes you need a Kalashnikov.”

At the time Chaib was bodyguard to the group’s leader Fouad Belkacem.

He later led Sharia4Belgium himself.

Security sources say IS used Sharia4Belgium to find recruits willing to go and fight in Syria, like Chaib, or fanatics prepared to carry out terror strikes in Europe.

A source said: “Chaib had contact with members of the Brussels and Paris cells.

“He’s a significant figure.”

Choudary, 49, was nailed himself after avoiding arrest in Britain for two decades when he took an online oath of allegiance to IS — and urged his followers to do the same.

An Old Bailey jury convicted him of inviting support for a terrorist group.

He will be sentenced in three weeks and faces up to ten years.
