Russia warned Israel against its strikes on Iranian nuclear sites, saying it puts the world on the "brink of a catastrophe". Israel has struck nuclear facilities across Iran, including at Bushehr, Natanz, Isfahan, and Arak. It accuses Iran of seeking to build a nuclear bomb. Tehran says its nuclear program is for civilian energy purposes.

Israel repeatedly struck Iran’s largest enrichment site at Natanz and at its Isfahan nuclear complex. But the full extent of the damage to the country’s nuclear program—or Iran’s ability to race secretly toward a nuclear weapon—remains unclear.

After Israel's strikes, Iran retains its scientific expertise, and now has a stronger incentive to bury its program even deeper.
