Three Iranians convicted of murder have been hanged in Tehran's Evin prison, a newspaper report said on Monday.
The men, identified only by their first names as Aziz, 25, Hassan, 25, and Mansoor, 34, were found guilty in separate cases and executed on Sunday, the Etemad newspaper said.
The latest hangings bring to 49 the number of people executed in Iran since the beginning of the year.
Iran executed 246 people in 2008, according to an AFP count.
The Islamic republic has stepped up its use of the death penalty since last year in what it says is a bid to improve security in society.
Amnesty International says Iran carried out more death sentences in 2007 than any other country, apart from China which executed 317 people.
Capital offences in Iran include murder, rape, armed robbery, drug trafficking and adultery.
