Israel unleashed airstrikes across Iran for a third day on Sunday and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country.

The Israeli Air Force (IAF) says it has destroyed "dozens" of radars and surface-to-air missile launchers as part of the attacks on Iran's air defence systems in the west of the country. Calling it a "large-scale strike", the IAF says this forms part of ongoing operations to damage Iran's air defence systems and those of its proxies.

The Israeli military warned Iranians living near nuclear reactors to evacuate, while Prime Minister Benjamin Netanyahu said the attacks by Israel so far were nothing compared with what Iran would see in the coming days.
