Iran's state TV has named a man that intelligence authorities allege was responsible for an attack at the Natanz nuclear site last weekend.
Reza Karimi fled Iran shortly before the blast, Network One said, showing a man's photo on what it said was an Interpol wanted poster.
Interpol said it could not confirm that Mr Karimi was on its red list of wanted fugitives.
Iran has blamed Israel for the attack and stepped up its nuclear activities.
Israel has neither confirmed nor denied involvement, but Israel public radio cited intelligence sources as saying it was a Mossad cyber-operation.
