Iran's ILNA news agency reported that an unspecified number of Kurdish lawmakers addressed their concern in a letter to the chief of the judiciary, Sadeq Larijani.

Their concern comes after an Iranian Kurd, Ehsan Fatahian, was executed despite the intervention of the lawmakers who claim he was earlier given a 10-year jail sentence by a lower court, ILNA said

The letter by the lawmakers says "a number of Kurdish youth have been given death penalties recently which is worrying the Kordestan province," ILNA said quoting the letter.

"The Islamic Republic of Iran must show its divine image in the country and outside... and the government should not act in a way that creates distance between Kurdish people and the regime," the letter added.

"Thus we earnestly ask the judiciary to reconsider issuing such verdicts after taking into consideration the international circumstances."

Last week the reformist website Mowjcamp which is close to Iranian opposition leader Mir Hossein Mousavi said that a Kurdish man Shirkouh Moarefi, 24, is also on a death row after he was convicted of being a "mohareb" (enemy of God), a crime punishable by death in Iran.

London based Amnesty International has asked the Iranian authorities to halt his execution.

The western province of Kordestan is dominated by Sunni Muslims and has seen deadly fighting in recent years between Iranian security forces and Kurdish rebels of the PJAK group operating out of rear-bases in neighbouring Iraq.

PJAK (Party of Free Life of Kurdistan) is closely allied with the Turkish Kurdish rebel group, the Kurdistan Workers' Party.

Kurds make up around seven percent of Iran's 70 million population.
