San Francisco Frontiers - US pushes naval coalition as Yemen rebels vow to attack more ships

The Iran-backed Huthis say their missile and drone strikes on passing container ships are in support of Palestinians in the Gaza war raging between Israel and militant group Hamas since October 7.

US Defense Secretary Lloyd Austin condemned the "unprecedented" spate of attacks in waters leading to the Suez Canal, a chokepoint for about 10 percent of global trade, that have forced many shipping companies to divert their vessels.

The task force, which Austin first announced late Monday, would include warships from the United States as well as Britain, Canada, France, Italy, the Netherlands, Norway and other countries.

The Pentagon chief, in Qatar on Tuesday after an Israel visit, told a virtual meeting with 43 countries, the EU and NATO that the attacks "threaten the free flow of commerce".

He urged other nations "to join US-led and other international initiatives... to restore security in the Red Sea to deter future Huthi aggression," the Pentagon said.

The Huthis voiced defiance and pledged to continue the attacks in the Bab al-Mandeb strait, a vital shipping lane between Asia and Europe.

"Even if America succeeds in mobilising the entire world, our military operations will not stop... no matter the sacrifices it costs us," senior Huthi official Mohammed al-Bukhaiti said on X, formerly Twitter.

The Huthis will only halt attacks if Israel's "crimes in Gaza stop and food, medicine and fuel are allowed to reach its besieged population," said Bukhaiti.

Rebel spokesman Mohammed Abdul Salam said the "US-formed coalition aims to protect Israel and militarise the sea. Whoever seeks to expand the conflict must bear the consequences of those actions."

- 'Threat to global economy' -

Britain said the Royal Navy destroyer HMS Diamond had joined the US-led task force, dubbed Operation Prosperity Guardian.

"These illegal attacks are an unacceptable threat to the global economy... and are threatening to drive up fuel prices," said UK Defence Secretary Grant Shapps.

Italy said it was sending the frigate Virgilio Fasan. And Spain said it would potentially also join, subject to "the decisions of the European Union and NATO".

The Huthi rebels have launched more than 100 drone and missile attacks, targeting 10 merchant vessels involving more than 35 different countries, according to the Pentagon.

On Monday, the Huthis claimed attacks on two more vessels, including the Norwegian-owned Swan Atlantic.

In November, the rebels seized the Galaxy Leader merchant vessel, taking its 25-member crew hostage. Both the vessel and crew remain in Yemen.

- 'Difficult to intercept' -

Insurance costs have soared, prompting major shipping firms to reroute their vessels around the southern tip of Africa, despite the higher fuel costs of much longer voyages.

Four of the world's biggest shipping companies -- CMA CGM Group, Hapag-Lloyd, Maersk and MSC -- have diverted their vessels, as has oil giant BP, in a move that sent up energy prices.

Denmark's Maersk on Tuesday said "all vessels previously paused and due to sail through the region will now be rerouted around Africa via the Cape of Good Hope".

Analysts however argue the maritime task force can do little to halt the attacks by the Huthis, who command an arsenal of ballistic missiles, cruise missiles and drones.

"The Huthis have an extended arsenal of different drones and missiles that they can shoot... and some of them will be difficult to intercept by your average navy ship," Andreas Krieg, a professor at King's College London, told AFP.

Torbjorn Soltvedt of risk intelligence firm Verisk Maplecroft said the "threat to shipping is also further increased by the group's ability to deploy anti-ship mines and execute coordinated operations using boats and helicopters."
