Ammon News - Several tanker owners, oil majors and trading houses have suspended crude oil, fuel and liquefied natural gas shipments via the Strait of Hormuz after the U.S. and Israel attacked Iran and Tehran said it had closed navigation, trading sources said on Saturday.

"Our ships will stay put for several days," one top executive at a major trading desk said. Satellite images from tanker trackers showed vessels backed up next to big ports, such as Fujairah in the United Arab Emirates, and not moving through Hormuz.

The British Navy said Iran's orders were not legally binding and advised vessels to transit with caution.

Greece's shipping ministry advised vessels on Saturday to avoid the Persian Gulf, the Gulf of Oman and the Strait of Hormuz, according to an advisory seen by Reuters.

Some 20% of global oil, including from producers Saudi Arabia, the United Arab Emirates, Iraq, Kuwait and Iran, passes through Hormuz along with large volumes of LNG from Qatar.
