Iran and Israel traded missiles and airstrikes on Saturday, the day after Israel launched a sweeping air offensive against its old enemy, killing commanders and scientists and bombing nuclear sites in a stated bid to stop it from 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.

In Israel, air raid sirens sent residents into shelters as waves of missiles streaked across the sky and interceptors rose to meet them, killing at least three people. An Israeli official said Iran had fired around 200 ballistic missiles in four waves.
