Iran has hanged a man it claims was an Israeli agent, who was convicted of the murder of an Iranian nuclear scientist.
Majid Jamali Fashi was found guilty last August of assassinating university professor Massoud Ali-Mohammadi.
The scientist was killed in January 2010 when a remote-controlled bomb attached to a motorbike went off outside his home.
Iranian state media said 24-year-old Fashi was a Mossad agent and had confessed to the killing. Iran’s Supreme Court approved his death sentence last week.
At the time of his murder, Iranian atomic agency said that Ali Mohammadi was not involved in its disputed nuclear programme, which Tehran maintains is for peaceful purposes.
Iran has accused Israel and the US of assassinating four Iranian scientists in an attempt to sabotage its activities. Washington has denied any role. Israel has remained tight-lipped.
Iran insists Fashi’s trial was fair but its not clear whether he was defended by a lawyer.
Last month Iran said it had arrested 15 people for allegedly plotting to assassinate another scientist.
A court statement alleges that the men were hired by Mossad and had meetings with Israeli officials in neighbouring countries.
