Tankers make sharp U-turns after Houthi shipping threat

Here is the latest breaking news from around the world: Tankers make sharp U-turns after Houthi shipping threatByThomas Copeland and Joshua CheethamBBC VerifyPublished48 minutes agoAt least seven oil tankers have made U-turns close to Yemen since the Iran-linked Houthi group announced a "maritime embargo" against Saudi Arabia on Monday, ship-tracking data shows. All of the ships were travelling either to or from Saudi ports and made sharp changes of course after the embargo was announced. Nearly 15% of global sea trade moves through the Red Sea, which connects the Mediterranean and Gulf of Aden through two choke points - the Suez Canal in Egypt and the Bab al-Mandab Strait between Yemen and the Horn of Africa.

The Red Sea has been a key route for exports of Saudi oil since the US-Israeli war with Iran led to the effective closure of the Strait of Hormuz, which has severely restricted the flow of oil and gas from the Gulf. This has played a "major role in relieving pressure to global markets" and if the Houthis further restrict trade then "prices will go up", said Rosemary Kelanic from the US-based Defense Priorities think tank. The day before the Houthis announced their blockade, 20 vessels entered the Red Sea and 22 exited via the Bab al-Mandeb strait, according to maritime intelligence firm Kpler.

The Details

Kelanic told Verify that any Houthi attacks on vessels in the Red Sea or Gulf of Aden "will suppress all international traffic not just Saudi-bound vessels". The EU's naval force in the region Aspides recommended on Wednesday that "merchant vessels linked to Israeli, US or Saudi interests avoid transiting the Red Sea and Gulf of Aden until the threat level decreases", according to an advisory seen by news agency. Ship-tracking data from MarineTraffic shows the crude oil tanker Rodos, loaded with Saudi crude, departed for India from the Red Sea port of al-Muajiz on Monday evening.

The Liberian-flagged ship set off south towards the Bab al-Mandab Strait but about nine hours later made a U-turn and began sailing north instead. The Liberian-flagged oil and chemical tanker Mica departed Saudi Arabia's Jazan port on Monday afternoon and also headed south before reversing course. Ship-tracking data shows at least eight ships bound for the Red Sea have made U-turns instead of entering the Bab al-Mandab Strait from the south as well.

Marshall Islands-flagged vehicle carrier Liu Jiang Kou was sailing to Saudi Arabia's Jeddah port from China before completely changing course on Monday in the Gulf of Aden. A Hong Kong-flagged crude oil tanker sailing from China called New Prime also turned around as it headed towards Saudi Arabia on Monday and now appears to be waiting in the Arabian Sea. While the reasons for each course change cannot be independently verified, "the timing is consistent with the embargo announcement," said maritime risk management company Vanguard.

In an email to shipowners on Monday, which the has seen, the Houthis said "vessels are banned from loading or discharging cargo at any Saudi ports".

The story has become one of the most prominent items on the global agenda.
