Iran says it has arrested 10 people who were working for Israel as "Mossad-related agents" in the province of West Azerbaijan.
The Islamic republic's judiciary announced the arrests on October 24 but did not give details, including who the people were or the day of their apprehension.
The judiciary said four of the 10 were accused of "corruption on Earth," a charge that carries the death penalty.
"Under the direct guidance of Mossad spy officers, [the group's members] were identifying forces that cooperated with the country's security departments and intended to release their personal information by kidnapping, threatening, and beating them," the judiciary said.
Israel neither denied nor confirmed the report, in line with its standard practice on such matters.
In early August, the Ministry of Information claimed to have identified a network of Mossad agents operating in the country and said that it had neutralized all of its operational elements.
Iran has been roiled by protests in recent weeks after the death of a young woman while in police custody after she was apprehended for allegedly wearing a head scarf, or hijab, improperly.
Tehran has blamed the unrest on the United States, Israel, and other Western actors looking to destabilize the country.
