Direct proof of use
Quds-1 use in the 2014 Yemen Civil War is documented in specialist missile-war research and open-source missile-identification work. CSIS states that the Houthis used the Quds-1 in at least three attacks: the June 2019 strike on Abha International Airport, a later June strike targeting the Shuqayq desalination plant, and an August 2019 strike against Abha airport.
IISS describes the Quds as a likely Iranian-origin cruise missile and identifies it as the Houthis' longest-range precision-strike system, used against Abha airport in Saudi Arabia in June 2019. Fabian Hinz's Arms Control Wonk analysis ties the Saudi-released Abha wreckage imagery to the Quds-1 rather than to the Ya Ali or Soumar labels used in early public discussion.

Timeline
The public use record begins in June 2019, when a cruise missile fired by Houthi forces struck Abha International Airport in southern Saudi Arabia and injured civilians. Saudi officials initially identified the missile as an Iranian Ya Ali, but later open-source analysis compared the wreckage with the Quds-1 displayed by the Houthis in July 2019 and found the Quds-1 identification more consistent.
CSIS records a second June 2019 Quds-1 shot against the Shuqayq desalination plant and another Quds-1 attack on Abha airport in August 2019. The July 2019 Houthi display of the Quds-1 came between those attacks and made the missile's external configuration publicly visible.

Narrative
In Yemen-war service, the Quds-1 functioned as a Houthi-aligned long-range land-attack weapon for strikes beyond the immediate ground front. The documented targets were in Saudi Arabia rather than inside Yemen, but the attacks were part of the wider Houthi missile and drone campaign connected to the Saudi-led coalition's intervention in the Yemen Civil War.
The public record separates three categories of evidence. First, CSIS and IISS directly document Quds or Quds-1 combat use by the Houthis against Saudi targets in 2019. Second, the July 2019 Houthi display and Arms Control Wonk wreckage comparison support the identification of the Abha missile as Quds-1. Third, UN Panel reporting and U.S. Defense Intelligence Agency material support the assessment that the system was not a purely indigenous Yemeni development and belonged to a broader Iranian-enabled Houthi missile arsenal.
The evidence is more specific for missile type and target category than for complete battle-damage outcomes. The best-supported Yemen-conflict claims are that Houthi-aligned forces fired Quds-1 missiles in 2019, that at least one Abha airport strike is tied to Quds-1 identification, and that the system served the long-range precision-strike role in the Houthi campaign against Saudi infrastructure and airport targets.
