Iran says its military action against US air bases in Iraq has "concluded" after around 15 cruise missiles targeted three separate US installations in retaliation for last week's American assassination of General Qasem Soleimani.

At the White House, President Trump postponed plans to make an address to the nation, and writing on Twitter after the attacks said simply "all is well".
