Biden says administration mulling re-designating Yemen's Houthis a terrorist group

US President Joe Biden said on Wednesday his administration is considering re-designating Yemen's Houthi movement as an international terrorist organization following drone and missile attacks on the United Arab Emirates claimed by the group.

His comment at a news conference came shortly after the Emirati Embassy said on Twitter that UAE Ambassador Yousef Al Otaiba urged the Biden administration to restore the designation in response to Monday's strikes on Abu Dhabi airport and a fuel depot.

Asked if he supported returning the Iran-aligned Houthis to the US list of foreign terrorist organizations, from which they were removed nearly a year ago, Biden replied, "The answer is, it's under consideration."

But he conceded that "it's going to be very difficult" to end the conflict pitting the Houthis against Yemen's internationally recognised government and a Saudi-led military coalition, to which the UAE belongs.

Biden's comment reflected the lack of progress toward ending the war since he launched an initiative shortly after taking office a year ago to bolster UN efforts to restart peace talks.

The UAE welcomed Biden’s comment, the Emirati Embassy said on Twitter. The “case is clear – launching ballistic and cruise missiles against civilian targets, sustaining aggression, diverting aid to Yemeni people,” it said.

Saudi Arabia's ambassador to Yemen, Mohammed Al Jaber, said on Twitter on Thursday that the United Nations and global community must not show leniency and hold the Houthi movement accountable because "it encourages other terrorist organisations to act similarly".

As part of the initiative he launched last year, Biden appointed veteran US diplomat Timothy Lenderking a special envoy. The State Department also reversed a last-minute Trump administration decision placing the Houthis on the US list of foreign terrorist groups, subjecting them to financial sanctions.

Three people were killed in Monday's drone and missile attack claimed by the Houthis.

In response, the Saudi-led coalition on Tuesday staged air strikes on the Houthi-held capital, Sanaa.

Otaiba held "broad" consultations with Biden's national security adviser, Jake Sullivan, on the situation that included discussions of the Houthi attack, a National Security Council spokesperson said.

The UAE Embassy said that Otaiba was accompanied by the top UAE intelligence official, Ali Al Shamsi.

The embassy, in a second Twitter post responding to Biden's consideration of the terrorist designation, said Otaiba pressed the case for re-designating the Houthis in his meeting with Sullivan.

"Austin conveyed his condolences for the loss of life, and underscored his unwavering support for the security and defense of UAE territory against all threats," the Pentagon said.
