Iran has asked Interpol to help arrest a suspect in a sabotage attack on its Natanz nuclear facility which it blames on Israel, a local newspaper reported yesterday. National television has published a photo and identified the man as 43-year-old Reza Karimi, saying the intelligence ministry had established his role in last week's "sabotage" at Natanz. The broadcaster said the suspect had "fled the country before the incident". A "small explosion" hit the Natanz plant's electricity distribution system a week ago, according to the Atomic Energy Organization of Iran. The Iranian foreign ministry accused arch-foe Israel of an act of "nuclear terrorism" and vowed revenge.
