SANAA, Yemen

US and British warplanes launched fresh airstrikes against Houthi sites in Yemen on Monday, according to the Yemeni group.

Six strikes targeted Jabanah district in the coastal Al Hudaydah province, the Houthi-run Al-Masirah television said.

US and British planes also carried out four airstrikes in Al-Faza district in the same province, the broadcaster said.

No reports were yet available about casualties or damage.

There was no immediate US comment on the report.

The Houthis have been targeting cargo ships in the Red Sea owned or operated by Israeli companies or transporting goods to and from Israel in solidarity with the Gaza Strip, where more than 31,700 people have been killed in a deadly Israeli offensive since last October following a Hamas attack.

With the US and UK launching retaliatory airstrikes against Houthi sites inside Yemen, the Houthis declared that they consider all American and British ships military targets.

A coalition led by the US - under the name Operation Prosperity Guardian - has conducted intermittent airstrikes since Jan. 12 that have targeted Houthi sites in parts of Yemen in response to the attacks in the Red Sea.

The Red Sea is one of the world's most frequently used sea routes for oil and fuel shipments.
