Riyadh | US Secretary of State Mike Pompeo on Thursday (AEST) called the attack on Saudi Arabia's oil installations an "act of war" against the kingdom by Iran, as the Saudis displayed missile and drone wreckage and cited other evidence they said showed the raid was "unquestionably sponsored by Iran".
Iran, which has denied involvement in the attack, warned the US it would retaliate immediately if it is targeted.
