A Dutch-Iranian woman, arrested after taking part in anti-government protests in Iran, has been hanged for drug smuggling, Iranian officials have said.
Sahra Bahrami, 46, was jailed for a year after being arrested after joining a protest in 2009, while visiting relatives. Dutch officials had said they were extremely concerned about her case.
Her execution brings the total number hanged in the country so far this year to 66, according to media reports.
During a search of her house, authorities found 450g of cocaine and 420g of opium, the Tehran prosecutor's office said.
"A drug trafficker named Sahra Bahrami, daughter of Ali, was hanged early on Saturday morning after she was convicted of selling and possessing drugs," the office said.
It added that Bahrami was a member of an international drug gang who smuggled cocaine into the country using her Dutch connections. Bahrami's daughter was quoted as saying the drug charges were fabricated.
