WASHINGTON — U.S. and Iranian officials exchanged fresh warnings on Friday as regional mediators intensified efforts to prevent the collapse of a fragile diplomatic framework, with negotiations aimed at preserving a broader agreement continuing despite renewed military and political tensions.
President Donald Trump repeated that the United States was prepared to increase pressure if Iran failed to meet commitments related to maritime security and ongoing negotiations, while leaving open the possibility of further talks. U.S. officials said Washington continued to coordinate with regional partners pursuing de-escalation efforts.
Iranian officials responded by warning that additional U.S. military action would prompt retaliation, while maintaining that Tehran remained prepared to pursue diplomacy if its conditions were respected. Iranian statements continued to dispute U.S. interpretations of previous understandings governing security in and around the Strait of Hormuz, according to official comments carried by state media and regional diplomats.
Diplomatic efforts led by Qatar, Pakistan, Egypt and Saudi Arabia continued through a series of contacts with both governments, officials familiar with the mediation said. Those discussions have focused on securing an immediate reduction in hostilities before attempting to resume technical negotiations on longer-term issues, including maritime security, sanctions and Iran's nuclear program.
The renewed exchanges followed several days of military escalation after Washington accused Iran of violating earlier commitments affecting commercial shipping in the Strait of Hormuz. U.S. officials said messages outlining Washington's demands had been delivered directly and through mediators, including a request that Tehran publicly affirm the safety of commercial navigation. Iran has rejected the U.S. characterization of recent events.
Vice President JD Vance said diplomacy remained an important component of U.S. policy even as military pressure continued, while administration officials maintained that negotiations would remain possible if Iran demonstrated compliance with agreed commitments.
The Strait of Hormuz remains central to the dispute because it handles a significant share of global oil shipments, and continued instability has raised concerns over energy markets and regional security. Previous negotiations produced an interim memorandum intended to halt fighting and establish a framework for broader talks, but repeated exchanges of fire have placed that arrangement under increasing strain.
As of Friday, mediators said contacts with both sides were continuing, and no official announcement had been made that negotiations had been terminated.
