'Make or break': What to know about US-Iran talks in Pakistan

US and Iranian officials are meeting in Islamabad for high-stakes ceasefire talks mediated by Pakistan. The US delegation is led by Vice President JD Vance, a move seen as a significant step-up in seriousness. However, Iran's speaker of parliament, Mohammad Bagher Ghalibaf, has stated that the US must first unblock over $100 billion in frozen Iranian assets and ensure a ceasefire in Lebanon before discussions can commence. President Trump has maintained a hardline stance, while the Pakistani Prime Minister has described the talks as a "make or break" moment. The key deliverable may simply be the willingness of all parties to meet again.
