Earlier this month, British counter terrorism police said Iran alongside Russia and China is behind a growing number of life-threatening operations on UK soil including assassination and kidnapping plots carried out by criminal proxies.
Additionally, the European Union sanctioned an Iran-linked network over their alleged role in assassination plots and enforced disappearances of dissidents abroad, including on European soil.
A new UK parliamentary report this week classed Iran is one of the most aggressive state actors targeting individuals in the United Kingdom.
Since January 2022, there have been at least 15 attempts at murder or kidnap against British nationals or UK-based individuals, according to a report by UK Parliament’s Intelligence and Security Committee (ISC) this month.
Iran has previously been accused of involvement in the kidnapping and killing of foreign nationals abroad.
In 2020, German-Iranian dissident Jamshid Sharmahd was kidnapped by Iranian operatives from Dubai and forcibly taken to Iran via Oman. He was sentenced to death and executed in what Amnesty called a "grossly unfair trial" in 2023.
Iran also abducted dissident journalist Rouhollah Zam from Iraq after luring him to leave Paris for the Arab country in September 2019. He was later sentenced to death and executed in Iran in 2021.
