Iran and Israel traded missiles and air strikes on Saturday, the day after Israel launched a sweeping air offensive against Iran, killing commanders and scientists and bombing nuclear sites in a stated bid to stop it building an atomic weapon.

In Tehran, Iranian state TV reported that around 60 people, including 20 children, had been killed in an attack on a housing complex, with more strikes reported across the country.

Israel said it had attacked more than 150 targets.

In Israel, air raid sirens sent residents into shelters as waves of missiles streaked across the sky and interceptors rose to meet them.

At least three people were killed overnight. An Israeli official said Iran had fired around 200 ballistic missiles in four waves.

US President Donald Trump has lauded Israel’s strikes and warned of much worse to come unless Iran quickly accepts the sharp downgrading of its nuclear programme that the US has demanded in talks that had been due to resume on Sunday.

But with Israel saying its operation could last weeks, and urging Iran’s people to rise up against their rulers, fears have grown of a regional conflagration dragging in outside powers.
