A crude oil tanker was struck on its port side by an unknown projectile in the Strait of Hormuz, the UK Maritime Trade Operations (UKMTO) said Wednesday. The agency received a delayed report from a verified source about Tuesday's incident but did not identify the vessel or disclose details about casualties, damage or the projectile's origin. Authorities are investigating, no group immediately claimed responsibility, and the incident occurred amid disputes between Iran and the US over navigation through the strategic waterway. Washington and Tehran signed a June memorandum of understanding on freedom of navigation, but implementation later stalled over security-related disagreements. The US and Israel launched a war against Iran in February, followed by Iranian attacks on Israel and US targets in the region, before a ceasefire agreement was reached in April.
