"Iran strongly condemns the blatant crime and the anti-human rights move by the Zionist regime (of Israel) in torturing and martyring the Palestinian prisoner, Arafat Jaradat," the Iranian foreign ministry said in the statement on Tuesday.
The statement further called on the relevant international and human rights organizations to take swift and on time move to prevent repetition of the human tragedies underway against Palestinian prisoners and against the international conventions.
Earlier, Palestinian Minister of Prisoners Affairs Eissa Qaraqe' said autopsy revealed that Palestinian prisoner Arafat Jaradat died of torture.
"Traces of severe torture appeared on Jaradat's body, neck, face and backbone," Qaraqe' told reporters in the West Bank city of Ramallah.
Initial Israeli media reports cited sources suggesting that Jaradat died of a heart attack. Qaraeq' denied this claims, describing it as "untrue Israeli claim."
"There was no signs of a heart attack or stroke," Qaraqe' said.
Jaradat's death angered Palestinians who have been protesting for several days to support the Palestinian prisoners in Israeli jails, specially the four prisoners, who have been on a hunger strike for months and demanded an end to their administrative detention, in which they could be locked up for long period without a trail.
The New York-based Human Rights Watch (HRW) called on Israel on Sunday to either charge or release the hunger-strikers immediately.
Yesterday, at least 26 protesters sustained wounds from rubber and live bullets during clashes near Ofer prison, West of Ramallah.
