Reacting to a U.S. offer to talk with Iran without pre-conditions, Iranian President Hassan Rouhani said on Sunday it was Washington that had left the negotiating table, and it "should return to normal state".

U.S. Secretary of State Mike Pompeo said on Sunday the United States is prepared to engage with Iran without pre-conditions about its nuclear program, but needs to see the country behaving like "a normal nation".

Rouhani was quoted by the government's official website as saying: "The other side that left the negotiating table and breached a treaty should return to normal state. Until then, we do not have a choice but resistance."
