US President Donald Trump on Friday voiced frustration with Iran's stance in nuclear negotiations but said he had not yet decided whether to carry out a threatened attack, as US staff were authorised to leave Israel due to heightened risks.
Trump has ordered the biggest military build-up in decades in the Middle East, with the world's largest aircraft carrier, the USS Gerald R. Ford, approaching the coast of Israel, as he demands Iran agree to sweeping concessions on concerns starting with its nuclear program.
A day after the United States and Iran held talks in Geneva, Trump said that the cleric-run state was "not willing to give us what we have to have" but added on military force, "We haven't made a final decision."
"We're not exactly happy with the way they negotiated. They cannot have nuclear weapons, and we're not thrilled with the way they're negotiating," Trump told reporters.
"We want no nuclear weapons by Iran and they're not saying those golden words."
Iran has said repeatedly that it is not pursuing nuclear weapons and agreed to restrictions on enrichment in a 2015 deal that Trump ripped up during his first term in office.
