High-stakes negotiations between Iran and the United States continue into the ninth hour of the morning, with negotiations taking place in Islamabad, Pakistan. The talks are being led by US Vice President JD Vance and Iranian parliamentary speaker Mohammad-Bagher Ghalibaf. The issue of control of the Strait of Hormuz, a vital route for global oil and liquefied natural gas shipments, is also a key issue. It is unclear how long the talks will continue, with suggestions that they may be extended into the following day.
