Qatar is mediating between the United States and Iran as their conflict enters its eighth month, but separate meetings with officials from both sides have not produced a ceasefire agreement or a deal to reopen the Strait of Hormuz. A two-page Qatari proposal addressed Iran’s demand to lift the U.S. naval blockade and Washington’s demand for nuclear concessions. U.S. officials said President Donald Trump was open to sanctions relief and releasing frozen Iranian funds for concrete nuclear steps, but Trump said he had offered Iran nothing. Tehran says it is open to negotiations without coercion, while insisting on its right to a civilian nuclear program and linking possible concessions to a U.S. return to the June memorandum of understanding. The conflict has killed thousands, disrupted energy supplies and contributed to inflation; oil prices fell 2.5% Tuesday, while Washington offered up to 40 million barrels from the Strategic Petroleum Reserve and sanctioned 10 individuals and entities accused of helping Iran procure weapons and components.
