More ships reroute in Red Sea after Houthi threats

Four tankers have changed course in the Red Sea, with two signalling the Suez Canal as their new destination after Yemen’s Houthi militia warned ships to avoid sailing to Saudi Arabian ports, ship-tracking data showed.

The Iran-aligned Houthis on Monday declared a naval blockade against Saudi Arabia, opening a potential new front against the United States in its war with Iran and raising the threat to global energy supplies and trade beyond the Gulf.

“The threat of Houthi hostile actions against Saudi Arabia … has begun to have an overall effect on tanker activity,” ship broker Clarksons said in a note on Wednesday.

“There are reports of several tankers, having loaded in Saudi Arabia’s Yanbu port in the Red Sea, that have shifted course towards the Suez Canal rather than sail south towards the Bab al-Mandeb strait, while others are holding their positions waiting for further instruction.”

Higher risk of attacks

Ships with links to Israel, the United States or Saudi Arabia are at a higher risk of being attacked by the Houthis and are advised to avoid voyages through the Red Sea and Gulf of Aden until the threat level decreases, the European Union’s Aspides naval force said on Wednesday in an advisory seen by Reuters.

Any vessel that recently called at, loaded cargo or discharged cargo at Saudi ports should “reduce its electronic footprint by minimising AIS (ship-tracking) transmissions and limiting any publicly accessible digital information that could facilitate targeting”, the advisory said.

The four tankers all changed direction, two of which signalled their destination as open waters in the Red Sea, according to LSEG and MarineTraffic ship-tracking data and analysis from British maritime risk-management group Vanguard.

A fifth ship — a vehicle carrier called Liu Jiang Kou — appeared to have turned away in the Gulf of Aden on Wednesday after signalling the Saudi Red Sea port of Jeddah as its next destination, shipping data showed. The vessel’s manager, China’s COSCO Shipping group, did not respond immediately to a request for comment.

Three oil tankers loaded with Saudi crude for China and India made U-turns in the Red Sea on Tuesday, heading towards the Suez Canal rather than braving the Yemeni coast. One of these tankers included the Xin Long Yang, managed by COSCO.
