April 17 (UPI) – Iranian intelligence officials on Saturday identified a suspect in an explosion at a nuclear facility in Natanz earlier this week.
Iran's Mehr news agency, quoting official television, reported an arrest warrant was issued by the intelligence ministry for Reza Karimi, 43, naming him as the instigator of the Sunday incident in which the Natanz facility lost power and a number of its centrifuges were damaged.
The officials said Karimi, an Iranian, fled abroad before the incident and so they issued an arrest warrant to Interpol.
No casualties or pollution were caused by the attack, which Iran blamed on Israel as an act of "nuclear terrorism."
