WASHINGTON (TNND) — Iran said Wednesday it has received the latest U.S. counterproposal aimed at securing a ceasefire and laying out a framework to end the conflict, as new reports of attacks on commercial vessels in the Strait of Hormuz underscored the high stakes for global energy markets.

Iranian authorities said Foreign Minister Abbas Araghchi presented the U.S. proposal to Iranian President Masoud Pezeshkian during a Cabinet meeting. The proposal reportedly calls for a seven-day ceasefire, though it was not immediately clear whether Washington accepted Iran’s broader conditions tied to reopening the Strait of Hormuz.

Iran has demanded sanctions relief for its oil sector, the release of frozen assets, an end to the U.S. naval blockade of Iranian ports and a seven-day ceasefire across the region.

Qatari mediators have been shuttling messages between the sides, but negotiations have made limited progress as the U.S. and Iran remain divided over key concessions. The counterproposal follows talks in New York last week involving Araghchi and U.S. envoys Steve Witkoff and Jared Kushner.

Shortly after Iran received the counterproposal, three commercial vessels, including an oil tanker and an LNG tanker, were reportedly hit by unknown projectiles in the Strait of Hormuz. No immediate attribution or damage details were released.

Iran has maintained a blockade on commercial shipping through the strategic waterway since the conflict began in late February, while the U.S. has sought to restrict Iran’s oil exports through a counterblockade of its ports.

The Strait of Hormuz previously carried roughly one-fifth of the world’s oil and liquefied natural gas, raising concerns that stalled diplomacy and continued attacks could further rattle energy markets.

President Donald Trump denied a report that he had offered Iran sanctions relief in exchange for nuclear concessions.
