The report by IRAN daily says the executions were carried out Sunday in Tehran Evin prison as well as a prison in the city of Karaj, some 45 km west of the capital, Tehran.

It says all the men, who were only identified by their first names, had previous criminal convictions.

While Iranian authorities do not publish the number of executions in the country, human rights groups say scores of people have been hanged in Iran since the start of the year.  Crimes that are punishable by death penalty in Iran include drug trafficking, murder, rape, armed robbery and kidnapping.
