A man has been hanged in Iran after being accused of working as a spy for Israel.
Majid Jamali Fashi was executed after being found guilty of killing a nuclear scientist in 2010. He was convicted in August after a trial at a revolutionary court in Tehran.
Iranian state media said that Jamali Fashi was paid $120,000 to assassinate Professor Ali-Mohammadi, a lecturer at Tehran University, who died after a motorbike laden with explosives was detonated by remote control outside his home.
Fashi, whose official crime was reportedly "corruption on Earth", appeared in Iranian television in January to issue a confession for the killing.
He also detailed the Mossad operation and the intelligence he was said to have gathered.
However opposition groups in Iran have said Mohammdi was killed by the government for his anti-establishment views, and that Fashi's confession was made under duress.
Mohammadi is one of several Iranian nuclear experts who have been killed in suspected assassinations in recent years, as tensions over the country's nuclear programme have continued to rise.
Iran claims it is attempting to enrich uranium for peaceful purposes, but the US and Israel are adamant the country is attempting to build a nuclear bomb.
Meanwhile it was reported that four gay Iranian men are facing execution after being found guilty of sodomy, which is a crime under iran's Sharia law.
"I am horrified and saddened to have heard the news about these four men," London-based Iranian human rights lawyer Mehri Jafari was quoted by Pink News and LGBTQ Nation as saying.
"Not only with regards to the execution which is about to take place, but the fact that is beyond our control."
A spokesperson for Iran Human Rights said: "We have many reports indicating that prisoners are subjected to torture and forced confessions". He added: "Often the prisoners are sentenced based on the confessions they have made under torture".
