A crude oil tanker was struck on its port side by an unknown projectile in the Strait of Hormuz, a strategic waterway for global energy and commodity supplies, the UK Maritime Trade Operations (UKMTO) said Wednesday. The agency received a delayed report of Tuesday's incident from a verified source but did not identify the vessel or provide details on casualties, damage or the projectile's origin. Authorities are investigating, and no group immediately claimed responsibility. The incident comes amid tensions between Iran and the US over navigation through the strait, which has remained a point of contention in negotiations over control and management of the waterway. 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. Washington and Tehran signed a memorandum of understanding in June on freedom of navigation in the strait, but implementation later stalled over security-related disagreements.
