Iran war: What is happening on day 44 of the US-Iran conflict?

US-Iran talks in Islamabad have ended without a deal, with each side blaming the other for the failure. The 21-hour-long negotiations concluded on Sunday, jeopardising a fragile ceasefire. Iran's Ministry of Foreign Affairs said no agreement was expected in one session, while the US delegation claimed to have made a final and best offer. The talks failed to end fighting that has killed thousands, mostly in Iran, and sent global oil and gas prices soaring.
