High-level U.S. and Iranian delegations held direct negotiations in Islamabad, Pakistan, led by U.S. Vice President JD Vance and Iranian Parliament Speaker Mohammad Bagher Ghalibaf, which ended abruptly after approximately 21 hours without a peace agreement. Reports indicate possible return of negotiators this week, amid unverified claims of threats prompting the Iranian team's circuitous return journey. The talks occurred during a fragile two-week ceasefire in a conflict that has reportedly entered its seventh week.
