Iran blames Israel for sabotage at Natanz nuclear site

(AP) — Iran’s Foreign Ministry spokesman has blamed Israel for a sabotage attack at the underground Natanz nuclear facility.

Saeed Khatibzadeh made the comment Monday, warning Iran would avenge the assault. Israel has not claimed responsibility for the attack, though media there almost uniformly say an Israeli cyberattack caused it.

Details remained scarce about what happened early Sunday morning at the facility. The event initially was described as a blackout caused by the electrical grid feeding its above-ground workshops and underground enrichment halls.

The assault could imperil ongoing talks in Vienna with world powers about saving a tattered accord aimed at curbing Iran’s nuclear program.
