US president Donald Trump will decide whether to join Israel's offensive against Iran within two weeks, the White House said on Thursday, potentially lessening the prospect of immediate military action.
Oil futures fell following the comments, with August Brent futures dropping by as much as 2.7pc to a low of $76.72/bl in Asian trading. US markets were closed on Thursday for a public holiday.
"Based on the fact that there's a substantial chance of negotiations that may or may not take place with Iran in the near future, I will make my decision whether or not to go within the next two weeks," Trump said, in a message read out by White House press secretary Karoline Leavitt.
Trump has repeatedly hinted in recent days that the US may join Israel's bombing campaign against Iran. "I may do it. I may not do it. I mean, nobody knows what I'm going to do," he said on 18 June.
Trump has also previously set two-week deadlines for other major decisions that have subsequently lapsed without action being taken, most recently in late May, when he gave Russian president Vladimir Putin two weeks to show he was serious about ending the war in Ukraine.
