Houthis say they attacked three US warships in Red Sea

The Houthis' military spokesman said operations will not halt until Israel's offensives in Gaza and Lebanon stop.

The group attacked Tel Aviv with a ballistic missile and launched a drone towards Ashkelon in southern Israel, Yahya Sarea said.

"We will carry out more military operations against the Israeli enemy to triumph for the sake of our brothers' blood in Palestine and Lebanon," he added in a televised speech.

Sarea also said, in a separate televised speech, that the group had simultaneously targeted three US destroyers in the Red Sea with 23 ballistic and winged missiles and a drone while the vessels were on their way to support Israel.

Israeli strikes have killed more than 600 people in Lebanon since Monday, with the conflict between Israel and Hezbollah at its most intense in more than 18 years.

Hezbollah has been firing rockets into Israel for almost a year in support of allied Palestinian militant group Hamas, which is fighting Israel in the Gaza Strip.
