US President Donald Trump said he will announce his decision on the US participation in the nuclear accord between Iran and world powers on May 8.
"I will be announcing my decision on the Iran Deal tomorrow from the White House at 2 p.m.," Trump tweeted on May 7.
The announcement comes ahead of a May 12 deadline for the US administration to decide whether to keep supporting the landmark 2015 nuclear deal or reimpose sanctions on Iran.
Trump has threatened to pull out of the deal by not extending sanctions waivers when they expire on May 12, unless European signatories of the accord fix what he has called "serious flaws."
Meanwhile, the foreign ministers of Germany and France have joined Britain’s foreign minister in a public push to convince Trump not to pull out of the nuclear deal.
Trump has also accused Iran of violating the spirit of the accord by supporting militant activity in the Middle East and by continuing to test ballistic missiles.
