Iran urged the United States on Monday to address the Islamic Republic with respect, not threats of war, a day after U.S. President Donald Trump stoked concerns about a potential U.S.-Iran conflict.

But in a sign of brewing confrontation a year after Washington quit world powers’ 2015 nuclear deal with Iran and reimposed sanctions on it, Tehran announced a fourfold increase in its rate of production of low-grade uranium enrichment.

On Sunday, Trump tweeted: “If Iran wants to fight, that will be the official end of Iran. Never threaten the United States again!”

Iranian Foreign Minister Mohammad Javad Zarif replied on his Twitter account “NeverThreatenAnIranian. Try respect—it works!”
