U.S. President Donald Trump's new threats will have no effect on Iran, the country's top negotiator, Mohammad Bagher Ghalibaf, said in comments carried by state media on Sunday.
"If you fight, we will fight, and if you come forward with logic, we will deal with logic," said Ghalibaf, who led his country's delegation to the talks along with Foreign Minister Abbas Araqchi.
Trump said on Sunday the U.S. Navy would start blockading the Strait of Hormuz, raising the stakes after marathon talks with Iran failed to reach a deal to end the war, jeopardizing a fragile two-week ceasefire.
Ghalibaf blamed the U.S. for not winning Tehran's trust, despite his team offering "forward-looking initiatives".
Iranian officials said talks fell apart over two or three key issues, blaming what they called U.S. overreach. Ghalibaf, who noted progress in the negotiations, said it was time for the United States "to decide whether it can gain our trust or not."
