Two men, including a karate athlete, have been hanged in Iran after being convicted of killing Basij paramilitary force member Seyed Ruhollah Ajamian, it has been reported.

Mohammad Mehdi Karami and Seyed Mohammad Hosseini, who was a volunteer children’s coach allegedly took part in anti-regime protests following the death of Masha Amini.

Amini died last September in police custody after being arrested for not wearing a hijab - which was made compulsory in public after the 1979 Islamic revolution.

She fell into coma, with police accused of brutally beating her, leading to a wave of serious anti-Government protests across the nation.

Karami and Hosseini’s death means four people in connection with the protests have now been executed in Iran since September.

According to the CNN, Mohammad Hossein Aghasi, a lawyer advocating Karami, posted on Twitter that the athlete was not given final rights to speak to his family before his execution.

It is being reported that 41 protestors have been given death sentences in recent months.

Two men, Mohsen Shekari and Majidreza Rahnavard, were executed in December, with the latter being hanged publicly in Mashhad, convicted of "enmity against God".

Karami was convicted on December 5, with human rights group Amnesty International claiming the trial "bore no resemblance to a meaningful judicial proceeding."

Ye-One Rhie, German Parliamentary member, paid tributes to both on social media.

"The story of #SeyedMohammadHosseini is so sad," she wrote on Twitter.

"He lost both his parents.

"He visited their graves every Thursday.

"He coaches kids for free."

Earlier this week, an Iranian chess player Sara Khadem reportedly arrived in Spain after being urged not to return home in the wake of her decision not to wear a hijab in a tournament.

Concerns were raised over the safety of sport climber Elnaz Rekabi after she competed without a hijab at the Asian Championships in Seoul last November.

Last month, it was reported that footballer Amir Nasr-Azadani was facing execution for "campaigning for women's rights".

FIFAPRO, the global representative organisation for professional footballers, said it was "shocked and sickened" by the reports and called for the decision to be revoked.

Another footballer named Parviz Boroumand was also arrested after attending protests in Tehran.

At the FIFA World Cup in Qatar, Iran players chose not to sing the country's national anthem as a protest during the group stage matches, with fans booing from the stands.

In September 2020, wrestler Navid Afkari was executed, for allegedly stabbing a security guard to death and his involvement in demonstrations against the country's regime in 2018.

Back then, Afkari claimed he was tortured into making a false confession.
