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 there was no indication if lifting sanctions over Iran's nuclear programme was 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.
