Iran has executed three men accused of carrying out armed unrest during January's anti-government protests, according to state media.
Hassan Dioband, Hamid Kazemi and Reza Zanganeh were accused of throwing Molotov cocktails and grenades, using bladed weapons and firearms, and setting fire to public facilities in the city of Karaj, west of Tehran, Iran's state news agency Tasnim reported.
The executions are the latest in a series linked to the protests, including those of people accused of having ties to Israel and the United States.
The number of executions in Iran has increased since US-Israeli strikes on the Islamic Republic began in late February.
The protest movement initially sparked in December last year by the high cost of living rapidly evolved into widespread anti-government demonstrations that peaked on 8 and 9 of January.
Iranian authorities reported more than 3,000 deaths, and blamed the violence on "terrorist acts" orchestrated by the US and Israel.
However foreign-based NGOs gave higher figures and the BBC received multiple accounts from Iranians of security forces opening fire on unarmed protesters.
Tasnim reported that the three men were executed after the Supreme Court upheld their convictions and found them guilty of "participating in operational activities on behalf of the Israeli Zionist regime, the United States and hostile groups".
The damage allegedly included an electricity substation in Karaj which caused power outages in some areas.
Dioband was arrested on 11 January after investigations identified him as a suspect in attacks on public property and incitement to violence.
Ten others accused of taking part in the unrest under his supervision were later arrested.
Reuters news agency reports that they received prison terms of 5 to 10 years.
The latest executions in Iran come after the UN human rights chief Volker Türk said he was alarmed by the rise in death penalties .
In August, Türk said at least 56 people had been executed on national security-related charges since 19 March, including 27 in cases linked to January's nationwide anti-government protests.
Iran is thought to be the world's second-most prolific executioner after China. Last year, it put to death at least 2,159 people, according to Amnesty International.
The human rights group said that was the highest figure on record since 1981 and included 45 executions of suspected dissidents on national security-related charges.
