A Greek national has been charged with assisting a foreign intelligence service, believed to be Iran’s, over the targeting of a journalist working for the London-based television station Iran International, according to British police.

Counter-terrorism police said Ioannis Aidinidis, 46, who resides in Munich, Germany, was arrested over the weekend and had been charged under Britain’s National Security Act.

Aidinidis is due to appear at Westminster Magistrates’ Court within the coming hours.

Police said allegations were believed to relate to Iran and to the targeting of a British-based journalist at Iran International, which is critical of Tehran’s government. Officers said they did not believe there to be any wider threat to the public.

Iran’s Islamic Revolutionary Guard Corps (IRGC) has reported 24 ships crossed the Strait of Hormuz in coordination with Iranian authorities over the past 24 hours.

In a statement carried by Iran’s Fars news agency, the IRGC navy said it is allowing a limited number of ships to cross the strategic waterway via designated routes each day to “avoid congestion”.

Yesterday, the IRGC said 26 commercial vessels crossed Hormuz within 24 hours.
