US seizes tanker off Venezuela
An electrical fire broke out aboard a container ship at the Port of Los Angeles on November 22, 2025, triggering a major emergency response and shelter-in-place orders. The fire was nearly contained by November 23. The incident coincided with a broader window of maritime geopolitical tensions, including Ukrainian attacks on Russian shadow fleet tankers in the Black Sea and US seizures of tankers off Venezuela.
