Tehran: Iran hanged on Sunday five members of anti-revolutionary groups including a woman after convicting them of a series of bomb attacks, the official IRNA news agency reported.

The five, including the woman Shirin Alamhouli, were executed in Tehran's Evin prison, the agency said, quoting a statement from the capital's prosecution office.

The four others who were hanged were Farzad Kamangar, Ali Heidarian, Farhad Vakili and Mehdi Eslamian.

"They were convicted of carrying out terrorist acts, including bombings of government centres and public properties in several Iranian cities," the prosecutor's office said without giving the location of the bombings.

Alamhouli, Kamangar, Heidarian and Vakili belonged to the Kurdish minority of Iran, according to the European Union and several websites that report on human rights issues.

New York-based Human Rights Watch has previously said that Kamangar, a teacher, had been sentenced to death for having links with the Kurdistan Workers' Party (PKK), which has fought a deadly insurgency against Turkey.

Kamangar, Heidarian and Vakili were given the death penalty in 2006 and their sentences were condemned by the European Union.

Some websites have reported that Alamhouli, 28, was arrested in May 2008 in Tehran and charged with having ties with PJAK, an offshoot of PKK.

The websites said the fifth convict Eslamian was arrested in May 2008 for having links with the group Kingdom Assembly of Iran.

His younger brother reportedly was hanged two years ago for his role in the bombing of a mosque in the southern city of Shiraz in April 2008 which left more than a dozen dead and 200 wounded.
