Iran says there was damage to its Fordow and Isfahan nuclear sites from an earlier attack as the Israeli PM vows that "more is on the way".

Sirens sounded in Israel as Iran launched dozens of ballistic missiles in retaliation for Israel's strikes on its nuclear facilities.

In remarks before the UN Security Council, Iranian Ambassador Amir Saeid Iravani claimed that 78 people had been killed in Israeli attacks across Iran -- using the term "martyred" -- and that another 320 had been injured.

Israeli emergency services have said at least two people were killed in the strikes and dozens of people are injured.

The State Department told regional allies about Israel's plan to strike Iran, and indicated it wasn't a U.S. operation, four sources told CBS News.

The retaliatory strikes came after Israel attacked Iran, killing top military leaders and scientists. The assault destroyed an aboveground nuclear enrichment plant near Natanz, the head of the U.N. nuclear watchdog agency said.

“Trump has now praised Israel’s strike, affirmed US material support, and Israeli media is reporting his public opposition was a disinformation campaign to mislead Iran,” said Saagar Enjeti, rightwing co-host of the podcast Breaking Points. “So in other words Trump, not Israel, has made a mockery of all of us [who] wanted to avoid this war.”

Israeli strikes on Iran and Tehran’s vows of reprisals have brought the two Middle East adversaries closer to an all-out war, which also threatens to draw in the United States, at least to some degree.
