The Royal Navy’s HMS Diamond is to join the international task force protecting ships that travel through the Red Sea, after a spate of attacks by Houthi militia.
The UK said its move was in response to the deteriorating security situation in the region.
It comes after United Kingdom Maritime Trade Operations (UKMTO) on Monday noted an attack on at least one British ship off the port of Mokha in Yemen.
And today, British maritime security firm Ambrey has said it received information of a potential boarding attempt off the coast of Yemen.
On Monday, US defence secretary Lloyd Austin announced US ships will join with vessels from the UK, Bahrain, Canada, France, Italy, Netherlands, Norway, the Seychelles, and Spain as part of a new US-led multi-national naval force.
HMS Diamond was already in the region and on Saturday was reported to have shot down an attack drone suspected of targeting commercial ships, the first time the Royal Navy had downed an aerial target in anger since the 1991 Gulf War.
The Iran-backed Houthis, who have taken over swathes of territory in Yemen, are allies of Hamas, and have vowed to target vessels they believe are heading to and from Israel.
Defence Secretary Grant Shapps said in a statement: “These illegal attacks are an unacceptable threat to the global economy, undermining regional security and are threatening to drive up fuel prices.
“This is an international problem that requires an international solution. That is why HMS Diamond has joined Operation Prosperity Guardian.
“This new task force will protect shipping and vital trade routes in the Red Sea, where large amounts of goods and oil transit through to Europe and on to the UK.
“Our Royal Navy personnel are protecting British interests in an increasingly contested part of the world. Their valuable contribution to upholding peace and security should not be underestimated and we thank them for their service, especially during this festive period.”
