Iran said on Wednesday a sabotage team detained by its security forces were Kurdish militants working for Israel who planned to blow up a "sensitive" defence industry centre in the city of Isfahan, state media reported.
Iran's Intelligence Ministry had announced the arrests on Saturday amid heightening tensions with arch-enemy Israel over Tehran's nuclear programme, without giving the nationality of those detained.
The ministry said in a statement carried by state media that those detained belonged to the Iranian Kurdish opposition group Komala who had been recruited by Israel's spy agency, Mossad, and given high explosives for the attack.
