Iranian wrestler Navid Afkari, 27, faced a gruesome end.
The BBC reports he was executed by hanging on Saturday in southern Iran, in the city of Shiraz.
Afkari was sentenced to death for the 2018 protests in protest against the country’s regime.
The Iranian judiciary claims Afkari murdered the guard in protest.
According to audio tapes leaked from prison to the public, Afkari had said he was tortured to give confession, the BBC writes.
Iran has denied torture.
- Iran executed a young wrestler despite global opposition, the BBC tweeted on Saturday.
Many international parties took a stand on behalf of Afkar, but even Donald Trump’s appeal did not save the wrestler.
- I heard that Iran is going to execute a big and popular wrestling star, 27-year-old Navid Afkar, whose only act was an anti-government demonstration in the streets.
They protested “the deteriorating economic situation and inflation in the country,” Trump tweeted in early September, even though he misspelled Afkar’s name.

- We join the rage of the rest of the world that the Iranian regime has sentenced to death Navid Afkar, who was tortured for making false confessions because he took part in peaceful demonstrations in 2018.
The administration also tortured his two brothers and sentenced them to decades in prison.
Let them go!
tweeted Morgan Ortagus, a U.S. State Department spokesman.
In the past, Thomas Bach, director of the International Olympic Committee, and Dana White, the boss of the UFC, have been commented on with concern.
- The IOC is shocked by this news.
IOC President Thomas Bach had appealed directly to the Iranian president this week, asking for mercy for Navid Afkar while respecting the sovereignty of the Republic of Iran, the International Olympic Committee said on Saturday after the execution news.
Lawyer Hassan Younesi tweeted, according to the BBC, that contrary to some Iranian media reports, there is no video evidence of the guard's murder.
Brothers Vahid and Habib of the executed Afkar were sentenced to 54 and 27 years in prison for the same case.
The BBC reports that Navid Afkari was Iran's national champion in wrestling.
Wrestling is an extremely respected sport in Iran.
The country has won 43 wrestling medals at the Olympics - more than any other sport combined.
