Israel has carried out attacks on Iran's nuclear facilities, alleging Tehran was getting close to obtaining a nuclear weapon.

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.

The status of Iran's nuclear capability is surrounded by mystery even as that is a central question in the Iran-Israel conflict.
