The Israel Defense Forces (IDF) said it had struck an inactive nuclear reactor among dozens of targets in Iran, primarily in its capital, Tehran. Forty Israel Air Force jets were involved in the strikes overnight into Thursday, June 19, the IDF said.

Hidden away in a mountainside south of Tehran is an enrichment plant that is vital to Iran’s nuclear ambitions - and Israel’s attempts to dismantle them.

Strikes on Natanz, Fordow, Isfahan and elsewhere pose little regional radiation risk but could release plumes of toxic chemicals, experts say.
