Iran-US war latest: Trump warns ‘I’ll do what I have to do’ if Tehran breaks agreement as US waives sanctions on oil

President Donald Trump has warned Iran against breaking a ceasefire agreement as the US partially lifted sanctions on Iranian oil for the first time in decades.

“If Iran doesn’t live up to their agreement, or if they’re not behaving, I will do what I have to do,” Trump told reporters on Monday.

The US has partially lifted sanctions on Iranian oil exports following “encouraging” talks over ending their months-long war.

The Treasury on Monday issued a 60-day sanctions waiver that would allow Iran to sell oil in US dollars for the first time in decades.

However, Iran reportedly denied a claim by Vance that Tehran would allow nuclear inspectors back into the country following initial talks in Switzerland.

Vance said discussions with the International Atomic Energy Agency could be happening “as soon as today”. But Iran’s foreign ministry said Tehran had made “no new commitments” on nuclear inspections.

Iran’s lead negotiator, Mohammad Bagher Qalibaf, insisted on Monday that the Strait of Hormuz would be managed by Iran and follow international laws.

“Hopefully we can activate the strait again, in terms of passage, and bring prosperity back to regional and global economy,” he said.
