In a post on his X account on Thursday, Iranian Foreign Minister Abbas Araghchi said Tehran has not been informed of any allegations via “proper diplomatic channels”.

“Iran stands ready to engage to shed light on what has truly transpired, and we reiterate that UK authorities should afford our citizens due process,” he wrote.

The United Kingdom has arrested eight men, including seven Iranian nationals, as part of two investigations regarding alleged threats to national security.

 London’s Metropolitan Police confirmed the arrests on Sunday, saying five men, including four of the Iranian nationals, were detained on suspicion of “preparation of a terrorist act” while the other three were being held under national security legislation introduced in 2023 to counter the actions of hostile states.

They were arrested as part of a "pre-planned" investigation into an alleged plot to "target specific premises," the Metropolitan Police said, adding that the "affected site" was made aware and is being supported by police.

As part of a separate investigation led by the Met, three other Iranian men were arrested in London on Saturday.

The Met said three men — aged 39, 44 and 55 — were arrested under section 27 the National Security Act at separate addresses in north-west and west London, and had been taken into custody while searches continued.

In his post, Araghchi pointed to the stories in the media about the alleged involvement of Iranian nationals in a supposed plot to target the Israeli embassy in London and urged the UK to engage so that Tehran may assist any probe into credible allegations.

The top Iranian diplomat warned that third parties are resorting to desperate measures, including false flag operations, to derail diplomacy and provoke escalation.

“Timing and lack of engagement suggest that something is amiss,” he said.

In a post on his X social media account on Tuesday, the Iranian foreign minister called on the UK to respect the rights of Iranians arrested in Britain, underscoring Tehran's readiness to assist investigations in the incident.

“Disturbed to learn that Iranian citizens have reportedly been arrested by UK security services,” Araghchi wrote.
