US says prepared to talk to Iran 'with no preconditions'

US Secretary of State Mike Pompeo said Sunday his country was ready to talk with Tehran "with no preconditions", but with no indication lifting sanctions over Iran's nuclear programme is on the table.

The top US diplomat, who is considered a hawk on the Iran file, appeared to soften the US stance somewhat following weeks of escalating tensions with Tehran.

"We are prepared to engage in a conversation with no preconditions," Pompeo said in Switzerland, which in the absence of US-Iranian diplomatic ties represents Washington's interests in the Islamic Republic.

"We are ready to sit down with them," Pompeo told a joint news conference with his Swiss counterpart Ignazio Cassis at the impressive medieval Castelgrande castle in Bellinzona, nestled in the Alps in Switzerland's Italian-speaking Ticino region.

He was reacting to comments made by Iranian President Hassan Rouhani on Saturday insisting that his country would not be "bullied" into talks with the United States, and that any dialogue between the two countries needed to be grounded in "respect".

But Pompeo appeared to immediately back-pedal on the offer to have condition-free talks with Iran, stating that Washington was "certainly prepared to have (a) conversation when the Iranians will prove they are behaving as a normal nation." -
But Pompeo stressed that "the American effort to fundamentally reverse the malign activity of this Islamic Republic, this revolutionary force, is going to continue."
I think that's very smart of them and I think there's a possibility for that to happen also."
But he stressed Switzerland could not be "mediators if there is not willingness on both sides."
"They're caused by 40 years of the Islamic regime not taking care of their people and instead using their resources to destroy lives."
