Aghil Keshavarz is the tenth person put to death for espionage since June conflict with Israel.

Iran has executed a man convicted of spying for Israel’s Mossad intelligence agency, judicial authorities announced, as Tehran continues a widening crackdown on alleged collaborators following the 12-day Israel-United States-Iran war earlier this year.

Aghil Keshavarz was put to death on Saturday morning after the Supreme Court upheld his conviction on espionage charges, according to Mizan, the judiciary’s official news agency.

The 27-year-old architecture student was arrested earlier this year in the northwestern city of Urmia after military patrols caught him photographing an army headquarters building.

The execution adds to a growing number of people put to death for espionage since the June conflict, with at least 10 executed by September alone.

In September, Iran executed a man it said was “one of the most important spies for Israel in Iran”.

In October, Tehran toughened legislation against alleged spies for Israel and the US, making espionage automatically punishable by death and asset confiscation.

According to the Mizan report, Keshavarz was accused of conducting more than 200 missions for Israeli intelligence services across Tehran, Isfahan, Urmia and Shahroud.

The missions allegedly included photographing target sites, conducting opinion polling, and monitoring traffic patterns at specific locations.

Authorities said he communicated with both Israel’s Mossad and military officials through encrypted messaging platforms, receiving payment in cryptocurrency after completing assignments.

The judiciary said Keshavarz had “knowingly cooperated” with Israeli services with the intention of harming Iran’s Islamic Republic.

The Oslo-based Iran Human Rights group has previously disputed similar espionage convictions, saying suspects are often tortured into false confessions.

Israel’s offensive in June involved 12 days of air attacks, including several against Iran’s top generals and nuclear scientists, as well as civilians in residential areas, for which Iran retaliated with barrages of missiles and drones. The US also carried out extensive strikes, on Israel’s behalf, on Iranian nuclear sites during the conflict. According to Amnesty International, Israeli attacks on Iran killed at least 1,100 people.

In response to the June war and protests in recent years over the state of the economy and women’s rights, as well as calls for regime change, Iran has sentenced more people to death.
