DUBAI, United Arab Emirates (AP) — Iran has blamed Israel for an attack on its underground Natanz nuclear facility that damaged its centrifuges. The sabotage imperils ongoing talks over Tehran’s tattered nuclear deal and brings a shadow war between the two countries into the light. Israel has not claimed responsibility for the attack. However, Israeli media widely reported that the country had orchestrated a devastating cyberattack that caused a blackout at the nuclear facility. While the nature of the attack and the extent of the damage at Natanz remains unclear, a former Iranian official said the assault set off a fire while a spokesman mentioned a “possible minor explosion.”
