LONDON (VINnews) — British prosecutors have charged two men with engaging in activities likely to assist a foreign intelligence service, the Crown Prosecution Service said Thursday. The charges follow a counter-terrorism investigation linking the alleged activity to Iran.

The men were arrested earlier this month as part of an investigation into the alleged surveillance of locations and individuals connected to the Jewish community in the London area, officials said.

The CPS statement did not provide further details on the men’s identities or the specific locations targeted, citing national security concerns.

Authorities said the case highlights ongoing vigilance against attempts by foreign states to gather intelligence in the UK. The investigation was led by Britain’s counter-terrorism police in coordination with other security agencies.
