The White House put Vice President JD Vance's planned Islamabad trip for US-Iran ceasefire talks on hold, saying confusion over the delegation's timing prevented departure. The pause comes as the existing ceasefire between Washington and Tehran is scheduled to expire in a few hours, creating a narrow window to negotiate an extension. The Associated Press and The New York Times ran live updates on the hold and the approaching deadline. Officials have not announced a new travel date for Vance, and failure to resume talks before the deadline could let the ceasefire lapse and raise regional tensions.
