A temporary ceasefire between the United States and Iran is set to expire with significant uncertainty over whether a new round of negotiations will take place, after Iran signalled it may skip scheduled talks in Pakistan on Tuesday. Political analysts are watching closely to see whether the diplomatic channel, which has included rare direct engagement between the two longtime adversaries, can be sustained. Meanwhile, human rights activists have urged the Trump administration to broaden its negotiating agenda beyond strategic concerns such as the Strait of Hormuz (a critical waterway through which a fifth of global oil passes) to include issues like internet freedom inside Iran.
