U.S. Vice President JD Vance says negotiations between the United States and Iran ended without a peace deal after the Iranians refused to accept American terms to not develop a nuclear weapon. The high-stakes talks in Pakistan ended after 21 hours, Vance said, with the vice president in constant communication with U.S. President Donald Trump and others in the administration. The war that has killed thousands of people and shaken global markets entered its seventh week.
