Federal prosecutors have accused Mohammad Baqer Saad Dawood al-Saadi of helping organize and promote a newly formed Iran-backed extremist organization allegedly linked to a wave of violent attacks across Europe.

According to court filings in the Southern District of New York, the group known as Harakat Ashab al-Yamin al-Islamiya (HIYA) reportedly emerged shortly after military tensions escalated between the United States, Israel, and Iran earlier this year.

Authorities claim the organization rapidly established operational cells capable of carrying out bombings, arson attacks, and stabbings targeting Americans and Jewish communities throughout Europe.

Prosecutors allege that within weeks of its formation, the group was connected to nearly 20 violent incidents, including attacks in Belgium, the Netherlands, and the United Kingdom.

Officials described HIYA as a possible front organization connected to Kata’ib Hezbollah, a militant faction long associated with Iranian-backed operations in the Middle East.

Court documents allege that al-Saadi, described as a senior figure connected to the organization, used encrypted messaging platforms and social media channels to encourage supporters to commit acts of violence.

One of the most alarming accusations involves messages allegedly calling for the assassination of Donald Trump. Prosecutors claim al-Saadi distributed threatening statements online alongside the HIYA symbol, urging followers to target Trump and support violent extremist activities.

Authorities further allege that after online calls for jihad were distributed through HIYA-linked channels, a series of antisemitic and anti-American incidents followed across Europe. Investigators cited attacks including synagogue bombings, arson incidents, and violent assaults targeting Jewish individuals.

Among the incidents referenced in court documents were a bombing near a synagogue in Belgium, attacks on Jewish ambulances in London, and stabbings involving Jewish victims in the United Kingdom.

The suspect was arrested in Turkey earlier this week after allegedly attempting to coordinate an arson attack targeting a synagogue in New York City through an undercover federal agent posing as a cartel associate.

Al-Saadi now faces multiple federal terrorism-related charges, including conspiracy to provide material support to terrorist organizations and conspiracy to attack public locations.

The case highlights growing international concerns over online extremist recruitment, transnational terror coordination, and rising antisemitic violence linked to geopolitical conflicts in the Middle East.

Security officials across Europe and the United States continue monitoring potential threats tied to extremist organizations operating both online and through decentralized international networks.
