STOCKHOLM -- Two Iranian-born Swedish brothers were on trial Friday in Sweden, charged with spying for Russia and its military intelligence service for a decade.
Peyman Kia, 42, and Payam Kia, 35, appeared before the Stockholm District Court to face charges of having worked jointly to pass information to Russia between Sept. 28, 2011, and Sept. 20, 2021.
Between 2014-15, Peyman Kia worked for Sweden's domestic intelligence agency but also for the country's armed forces. Swedish prosecutors allege that the d ata they gave the Russians originated from several authorities within the Swedish security and intelligence service.
Swedish media reported that Peyman Kia worked for the armed forces' foreign defense intelligence agency and worked with a top secret unit within the agency that dealt with Swedish spies abroad.
Even though many details remain unknown, intelligence expert Joakim von Braun told Swedish broadcaster SVT that it appeared to be one of most damaging cases of espionage in Sweden's history because the men compiled a list of all the employees within the Swedish security and intelligence service.
"That alone is a big problem because Russian intelligence focuses on human sources," von Braun said.
"The material is the absolute most secret material available," prosecutor Mats Ljungqvist told the court. "It is an unusual trial in that a similar case has not appeared in Sweden in over 20 years."
One of Sweden's largest spy scandals took place during the Cold War when Stig Bergling, a Swedish security officer who worked for the Swedish security and intelligence service and the armed forces, sold secrets to the Soviet Union.
He was sentenced in 1979 to life imprisonment on similar charges and later escaped while serving his time, returned voluntarily to Sweden in 1994. He died in his native country in January 2015.
Peyman Kia was arrested in September 2021 and his brother in November 2021. Both denied any wrongdoing, their defense lawyers told the court.
Payam Kia, 35, helped his brother and "dismantled and broke a hard drive which was later found in a trash can" when his brother was arrested, according to the charge sheet obtained by The Associated Press.
The naturalized Swedish citizens face sentences up to life imprisonment if convicted.
In a separate, unrelated case, Swedish authorities released Thursday one of two people arrested this week on suspicion of spying against Sweden and another, unnamed foreign power.
The released individual remains a suspect and authorities didn't explain why the other person was kept in custody.
The two were arrested Tuesday in a predawn operation in the Stockholm area. Authorities have given few details about the case, but Swedish media cited witnesses who described elite police rappelling from two Black Hawk helicopters to arrest them.
According to Swedish reports, the two are a couple and are Russians who arrived in Sweden in the late 1990s. The AP could not independently confirm these reports.
