US President Donald Trump has warned Iran that it must swiftly abandon any nuclear ambitions or face a military response as diplomatic efforts between the two nations resume, Reuters reported.

Trump made the comments following a meeting in Oman on Saturday between US special envoy Steve Witkoff and a senior Iranian representative. Both nations described the session as “constructive,” with a follow-up round expected this weekend, potentially in Rome.

Speaking to reporters, Trump voiced scepticism over Iran’s intentions. “I think they’re tapping us along,” he said. Despite the positive tone from the talks, he stressed Iran must fully renounce nuclear weapon development.

“Iran has to get rid of the concept of a nuclear weapon. They cannot have a nuclear weapon,” Trump said.

Asked if a military strike remains on the table, he replied, “Of course it does,” underlining the seriousness of his administration’s stance.

According to a source briefed on the discussions, the current talks are exploratory, aimed at gauging the potential for a broader agreement. Still, Trump insisted time is running out. “They’re fairly close” to developing a weapon, he said, calling for quick action to avoid a “harsh response.”

While the Biden administration held indirect talks with Iran, little progress was made. The last direct negotiations occurred under President Barack Obama, who spearheaded the 2015 nuclear agreement that Trump later withdrew from.

With tensions rising, the outcome of the next round of discussions may prove critical in determining the future of US-Iran relations.
