A ceasefire deal between Yemen's Houthis and the U.S. does not include sparing Israel, the group said Wednesday, suggesting its shipping attacks that have disrupted global trade and challenged world powers will not come to a complete halt.

President Donald Trump announced on Tuesday the U.S. would stop bombing the Iran-aligned Houthis in Yemen, saying that the group had agreed to stop attacking U.S. ships.

After Trump made the announcement, Oman said it had mediated the ceasefire deal to halt attacks on U.S. vessels.

There have been no reports of Houthi attacks on shipping in the Red Sea area since January.

"The agreement does not include Israel in any way, shape or form," Mohammed Abdulsalam, the chief Houthi negotiator, told Reuters.

"As long as they announced the cessation [of U.S. strikes] and they are actually committed to that, our position was self-defence, so we will stop."

While tensions may have eased between the United States and the Houthis, a resilient force that withstood years of heavy Saudi-led bombing in Yemen's civil war, the agreement does not rule out attacks on any other Israel-linked vessels or targets.

The U.S. intensified strikes on the Houthis this year to stop attacks on Red Sea shipping. Rights activists have raised concerns over civilian casualties.

"They said, 'Please don't bomb us any more and we're not going to attack your ships,'" Trump said of the Houthis during an Oval Office meeting with Canadian Prime Minister Mark Carney on Tuesday.

"And I will accept their word. And we are going to stop the bombing of the Houthis effective immediately."

U.S. has struck more than 1,000 targets

The Houthis have been firing at Israel and at shipping in the Red Sea since Israel began its military offensive against Hamas in Gaza after the Palestinian militant group's deadly attack on Israel on Oct. 7, 2023.

The U.S. military has said it has struck more than 1,000 targets since its current operation in Yemen — known as Operation Rough Rider — started on March 15. The strikes, the U.S. military said, have killed "hundreds of Houthi fighters and numerous Houthi leaders."

Tensions have been high since the Gaza war began, but have risen further since a Houthi missile landed near Israel's Ben Gurion Airport on Sunday, prompting Israeli airstrikes on Yemen's Hodeidah port on Monday.

The Israeli military carried out an airstrike on Yemen's main airport in Sanaa on Tuesday, its second attack in two days on Houthi rebels after a surge in tensions between the group and Israel.

Under former U.S. president Joe Biden's administration, the U.S. and Britain retaliated with airstrikes against Houthi targets in an effort to keep open the crucial Red Sea trading route — the path for about 15 per cent of global shipping traffic.

After Trump took over the U.S. presidency in January, he decided to significantly intensify airstrikes against the Houthis. The campaign came after the Houthis said they would resume attacks on Israeli ships passing through the Red Sea, the Arabian Sea, the Bab al-Mandab Strait and the Gulf of Aden.

On April 28, a suspected U.S. airstrike hit a migrant centre in Yemen, with Houthi TV saying 68 people were killed.
