"We will not stand idly by if the Americans are tempted to escalate further and commit foolishness by targeting our country or waging war against it," Abdel Malek Al Houthi said.
"Any American targeting of our country will be targeted by us, and we will make American battleships, interests, and navigation a target for our missiles, drones, and military operations," he said in a televised speech.

The Houthis have stepped up their Red Sea attacks, and warning shipping companies against dealing with Israeli ports.

Dubbed "Operation Prosperity Guardian", Britain, Bahrain, Canada, Denmark, France, Italy, the Netherlands, Norway, Seychelles and Spain, along with the US, will conduct joint patrols in the southern Red Sea and the adjacent Gulf of Aden.

"As long as the Americans want to enter into a direct war with us, they should know that we are not those who fear them, and that they are facing an entire people," al-Houthi said.

He warned the Americans against sending soldiers to Yemen, saying they would "face something harsher than what they faced in Afghanistan and what they suffered in Vietnam."
