Israel's strikes on Iran have targeted several of its nuclear facilities as it claims the country is seeking to develop nuclear weapons -- an accusation Tehran denies.

Blasts rang out across a swath of the Middle Eastern republic’s territory, targeting Iran’s nuclear capabilities, military leadership and scientists.

Israel has escalated its bombardment of Iranian cities, including Tehran's state television headquarters; Iranian missiles have struck Tel Aviv.

The International Atomic Energy Agency said Tuesday it believes Israeli airstrikes on Iran’s Natanz enrichment site have had “direct impacts” on the facility’s underground centrifuge halls. The strikes are part of an air campaign Israel launched against its longtime foe five days ago,

Iranian sites such as the Isfahan nuclear technology centre, Shiraz missile production facility, Tabriz north missile base, and more have been struck by Israel.

When Israel launched its series of strikes against Iran last week, it also issued a number of dire warnings about the country’s nuclear program, suggesting Iran was fast approaching a point of no return in its quest to obtain nuclear weapons and that the strikes were necessary to preempt that outcome.

Israeli strikes have damaged underground uranium enrichment facilities at Iran’s main nuclear fuel production site, the International Atomic Energy Agency (IAEA) said on Monday, citing analysis of satellite imagery taken after Friday’s attacks.

An Israeli military strike on Iran's nuclear complex at Natanz directly hit the underground uranium enrichment plant there, the U.N. nuclear watchdog said on Tuesday, revising its assessment after initially reporting it had been hit only indirectly.
