Israel's strikes on Iran's nuclear installations so far pose only limited risks of contamination, experts say. But they warn that any attack on the country's nuclear power station at Bushehr could cause a nuclear disaster.

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 has struck a series of nuclear facilities across Iran, including its largest enrichment site, Natanz, key buildings at its Esfahan complex, factories that make centrifuges to enrich uranium, and its still-under-construction heavy-water reactor at Khondab.
