The UN Security Council voted Monday to extend to all of Yemen's Houthis an arms embargo that until now targeted only some leaders of the Iran-backed militias.
Monday's resolution -- proposed by the United Arab Emirates, which is part of the Saudi-led Arab coalition -- was adopted with 11 votes in favor and four abstentions.
The UAE has been on heightened alert since a Houthi drone and missile attack killed three oil workers in the capital Abu Dhabi on January 17, the first in a string of attacks on what is usually viewed as a safe haven.
The Houthis have also regularly launched attacks against Saudi Arabia.
The resolution "strongly condemns the cross-border attacks by the Houthi terrorist group, including attacks on Saudi Arabia and the United Arab Emirates striking civilians and civilian infrastructure, and demanding the immediate cessation of such attacks."
The UAE mission to the UN said the "resolution will curtail the military capabilities" of the Houthis.
Saudi Arabia and the United States have long accused Iran of supplying the Houthis with sophisticated weapons, a charge Tehran denies.
The resolution states that the Houthi militias in their entirety will now be subject to an arms embargo, first declared in 2015 on some of their leaders.
