An Iranian man found guilty of adultery was stoned to death, despite an Iranian ban of the practice.
The victim, a government employee, 30, was said to have been executed in a prison in the northern city of Rasht.
Under Iran's Islamic law, people convicted of adultery can still be stoned to death. The offender is partially buried in a public spot, and stones are thrown at them until their dead unless they manage to free themselves.
In 2002, the executions were banned while the United Nations and European Union have called on Iran to abolish the punishment. However, five Iranians have reportedly been stoned to death in the past four years.
