Iran has sentenced to death four people accused of collaborating with Israel, the semiofficial Mehr News agency reported.
According to a report by Mehr News on November 30, the four were arrested in June and were accused of having interrogated people in Iran with intelligence cooperation from Mossad, the Israeli secret service.
Three other people on trial in the case were handed sentences by the Supreme Judicial Court of Iran of between five years and 10 years for "acting against the country's security," kidnapping, and the possession of weapons.
Iran and Israel have been engaged in a yearslong shadow war. Tensions between the two have soared in recent years.
The report on the sentencing comes after Tehran accused Israel of carrying out a recent spate of assassinations and sabotage attacks inside the Islamic republic.
Earlier this year, Israeli media reported that Mossad captured and interrogated a member of the Islamic Revolutionary Guard Corps inside Iran.
Later, a video was released in which a person who identified himself as Mansur Rasuli, admitted that he wanted to assassinate an Israeli diplomat working in the country's consulate in Istanbul, as well as an American general stationed in Germany and a journalist in France.
Mehr News has not specified whether the people who were sentenced to death were related to that case or not.
Iran has been roiled in recent months by nationwide protests sparked by the death of a young woman while she was being held in police custody for allegedly wearing a head scarf improperly.
Tehran has blamed Israel, the United States, and other Western countries for the unrest, which has seen security forces kill more than 400 people, according to human rights groups, including dozens of minors.
Officials have not shown any evidence to back up their accusations that the West has been involved in the anti-government uprising.
