US Vice President JD Vance left Pakistan after more than 21 hours of tense negotiations with Iran failed to produce a peace agreement to end the war, BBC reports.

“We've had a number of substantive discussions with the Iranians, that's the good news. The bad news is that we have not reached an agreement and I think that's bad news for Iran much more than it's bad news for the United States of America,” Vance said.

“We just could not get to a situation where the Iranians would accept our terms,” the US vice president added.

He emphasized that the issue of nuclear weapons is central to US-Iran talks and that President Trump’s main objective is to prevent Tehran from obtaining nuclear weapons, both now and in the future. According to Vance, during the talks in Islamabad, the United States did not see any commitment from Iran to refrain from developing nuclear weapons.
