Mizan said Keyvani was executed on Wednesday morning after his death sentence was upheld by the Supreme Court. He had been accused of passing “images and information of sensitive locations” to officers of Israel’s Mossad intelligence agency.
The report said Keyvani was arrested in Savojbolagh on the fourth day of the 12-day war in June. Authorities said the case had gone through legal procedures, but no independent evidence supporting the allegations was made public.
Later in the day, Swedish Foreign Minister Maria Malmer Stenergard said in a statement that a Swedish citizen was executed in Iran without naming him. However, it confirmed that the person was arrested in June.
The legal proceedings leading up to the execution did not meet the standards of due process, she added.
The semi-official Tasnim news agency said Keyvani had been detained by the Revolutionary Guards’ intelligence arm and was found with cash, vehicles and what it described as advanced communication and surveillance equipment.
Tasnim also reported that he had allegedly been recruited through online contact and trained abroad before returning to Iran, though these claims could not be independently verified.
Keyvani is the latest in a series of executions in Iran involving individuals accused of espionage for Israel, particularly since the outbreak of the June war.
Iran has one of the highest execution rates in the world and has long used the death penalty in national security cases, including allegations of spying. Following the conflict, rights groups and international media have reported a sharp increase in arrests and executions on such charges.
The Telegraph reported that executions in Iran have surged since the June war, citing data from human rights group HRANA indicating that the number of executions has risen significantly, including for those accused of links to Israel. The Sunday Times has also reported that dozens more people could face execution on similar charges.
