Iranian state television reported that a fourth oil tanker was involved in an accident in Hormuz on Friday, while Britain's Maritime Operations Authority said a crude oil tanker had been hit by a leak while crossing the strait. The Iranian Revolutionary Guards confirmed that the Mafra tanker that was attacked by a missile was carrying more than two million barrels of crude oil. Earlier on Friday, US Central Command denied Iran's accusations of destroying a US Navy ship in the Strait of Hormuz.
