Recap

Here's a quick recap of the developments from the past few hours: 

• Donald Trump said US air strikes had "completely and totally obliterated" three Iranian nuclear sites, as Washington directly joined Israel's assault on Iran. The president warned that if Iran did not make peace, the US would go after further targets 

• Iranian officials confirmed on Sunday that parts of nuclear sites were struck, including Fordow, the secretive Iranian nuclear enrichment facility buried half a kilometre under a mountain near the city of Qom. Sites in Isfahan and Natanz were also struck

• Iran's Atomic Energy Organisation, the government body responsible for nuclear energy, said that it would not allow the development of its "national industry" to be stopped 

• There had been "no signs of contamination" after the US strikes, and therefore there was no danger for inhabitants living near the sites, according to Iranian authorities 

• Israel was in "perfect coordination" with Washington over the strikes, Benjamin Netanyahu said. The Israeli prime minister praised a "bold decision" by Trump, saying it would "change history"

• Israel closed its airspace until further notice "due to recent developments", the Israel Airports Authority said

• The Israeli military raised the country's alert level following the US strikes. Schools and workplaces would be closed under the new restrictions, with the exception of "essential sectors"

• Antonio Guterres, the UN secretary-general, labelled the US strikes on Iran a "dangerous escalation in a region already on the edge - and a direct threat to international peace and security"
