Iranian authorities have executed a man convicted of supporting groups considered hostile to the government during anti-government demonstrations, according to the country’s judiciary.

Majid Adineh was put to death on Sunday after Iran’s Supreme Court rejected his appeal against a death sentence handed down by a Revolutionary Court in Karaj, the judiciary’s Mizan Online reported.

Authorities accused Adineh of participating in activities that threatened national security, including arson and organising with others to commit offences against the state.

He was arrested alongside another suspect on January 9 in Alborz province, near Tehran. Police reportedly found weapons and other items in their possession, including a firearm, ammunition, Tasers, tear gas canisters, a chainsaw and gasoline.

The protests began in December amid public anger over rising living costs and economic difficulties before developing into broader demonstrations against the Iranian government.

Iranian authorities have linked the unrest to foreign interference, particularly from the United States and Israel, and said more than 3,000 people died during the disturbances.

Adineh’s execution is part of a wider increase in executions in Iran since the outbreak of the Middle East conflict. Several of those put to death have been convicted in cases connected to the protests, while others faced charges related to the war.

Human rights organisations have repeatedly raised concerns over Iran’s use of the death penalty. Iran Human Rights and Together Against the Death Penalty reported that at least 1,639 people were executed in Iran in 2025, making it the country’s highest annual figure since 1989.

Amnesty International ranks Iran among the countries with the highest number of executions globally.
