The Houthis launched a drone attack on January 17, killing three foreign workers in the UAE capital, Abu Dhabi. The Saudi-led coalition fighting the Houthis responded with air strikes on the Yemeni capital that killed at least 12 people.

The Houthis launched missiles again on January 24, but the UAE intercepted those with support from the United States. After that attack, a Houthi spokesperson warned the group would “expand their operations over the next phase,” and warned foreign companies to leave the UAE.

Monday’s attack took place during Israeli President Isaac Herzog’s ongoing visit to the UAE. The President and his entourage were in no danger, and the visit is expected to continue as planned, an Israeli presidential spokesman said.

On Sunday, Herzog met with Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed Al-Nahyan in Abu Dhabi, and condemned terrorist attacks targeting the UAE, according to the UAE’s state news agency WAM.

Later on Monday, Herzog is due to visit the Dubai Expo before returning to Israel.

The UAE is a member of the Saudi-led coalition that has been at war for years with the Tehran-backed Houthi rebels, which control much of Yemen.

The offensive began in 2015 to restore Yemen’s internationally recognized government, after it was ousted by the Houthis. The coalition has intensified its attacks in the war-torn nation in the wake of the Houthi attacks on the UAE this month.

In 2019, the UAE pulled most of its troops from Yemen, after privately deeming the war unwinnable. The campaign failed to crush the rebels but exacted a huge humanitarian toll, with thousands of Yemenis dead and malnourishment and disease widespread.

More recently, the UAE has returned to the conflict, backing Yemeni groups in flashpoints like the oil-rich provinces of Shabwa and Marib.
