U.S. and Iran Exchange Fire in Strait of Hormuz as CIA Assesses Blockade Resilience

The United States and Iran exchanged fire in the Strait of Hormuz on Friday, May 8, 2026, marking the most intense fighting since a ceasefire began in April, while a CIA assessment revealed Tehran could endure a naval blockade for approximately four months, according to a U.S. official familiar with the intelligence. The finding underscores limited U.S. leverage as Washington awaits Iran's response to a proposal to formally end hostilities.

U.S. forces struck two Iran-linked vessels attempting to enter an Iranian port, damaging their smokestacks with a fighter jet and forcing them to retreat, the U.S. military said. Iran's Fars and Tasnim news agencies reported sporadic clashes but stated the situation had calmed, while Iran accused the U.S. of violating the ceasefire after a Navy attack on a commercial ship killed one crew member and left 10 wounded, with four missing. The Strait, a critical oil transit route, has been largely closed to non-Iranian shipping since the war began on February 28.

The United Arab Emirates intercepted two ballistic missiles and three drones launched from Iran on the same day, resulting in three moderate injuries, according to Emirati authorities. The attacks followed Iran's condemnation of President Trump's short-lived 'Project Freedom,' aimed at escorting ships through the strait. Iran's Foreign Ministry called the U.S. actions a breach of the ceasefire, while Secretary of State Marco Rubio urged NATO allies, including Italy, to support efforts to reopen the waterway.

The U.S. Treasury imposed sanctions on 10 individuals and companies in China and Hong Kong for aiding Iran's military drone program, warning of secondary sanctions on foreign financial institutions and airlines supporting Iran's illicit trade. The move targets supply chains linked to China's independent 'teapot' refineries and underscores broader economic pressure ahead of President Trump's scheduled meeting with Chinese leader Xi Jinping.

Secretary Rubio said Washington expected Iran's formal response to the peace proposal by May 8, but no reply had been received by mid-afternoon in Washington. The State Department confirmed talks remain ongoing, and the U.S. continues to coordinate with regional allies. The court will resume hearing on Tuesday.
