Britain warned the security situation in the Red Sea was deteriorating and ballistic missile and drone attacks were an increased threat, as it agreed for a Royal Navy Destroyer to join a U.S.-led operation to safeguard commerce in the region.

The United States said earlier Tuesday it was setting up a task force of ships to protect shipping in the Red Sea and Gulf of Aden, key trading routes, to protect shipping from the rising number of attacks launched by Houthis in Yemen.

The Houthis have stepped up attacks in response to Israel's assault on the Gaza Strip, forcing oil major BP and freight firms including Maersk to avoid the area.

Britain's Ministry of Defense (MoD) said Tuesday that HMS Diamond, which shot down a suspected drone in the Red Sea on Saturday, would join the U.S.-led international taskforce, as it warned of the rising threat levels.

"These illegal attacks are an unacceptable threat to the global economy, undermining regional security and are threatening to drive up fuel prices," Britain's defense minister Grant Shapps said in the statement.

"This is an international problem that requires an international solution."

Britain said that alongside HMS Diamond the task force currently includes three U.S. destroyers, and a French warship is in the region. They are operating in the Southern Red Sea, focusing on protecting freedom of navigation, international trade and human life by countering illicit non-state actors in international waters.
