Iran denies it was involved in the drone attack which killed three US troops and injured 34 on a US base in Jordan, near the Syria border

US President Joe Biden said the attack had been carried out by Iran-backed militant groups operating in Syria and Iraq

"We shall respond," he said at a campaign event in South Carolina on Sunday

It is the first time US soldiers have been killed by strikes in the region after Hamas's 7 October attack on Israel sparked the war in Gaza
