(CNN) The Saudi-led coalition fighting in Yemen on Saturday denied supplying Iranian-backed Houthi militia and al Qaeda-linked fighters with US-made weapons, according to a report from Saudi state media.

The coalition's denial comes on the heels of a CNN investigation published earlier this week that found Saudi Arabia and its coalition partners had supplied American-made weapons to al Qaeda-linked fighters, hard-line Salafi militias and other factions battling in Yemen -- a violation of their arms sales agreements with the United States.

Coalition spokesman Col. Turki Al-Malki "strongly denied those claims," per a report from the Saudi Press Agency, and said the idea that weapons were transferred to third parties was "illogical."

CNN captured on camera the weapons transferred to the Alwiyat Al Amalqa -- the Giants Brigade, an ultra-conservative Sunni militia. CNN also obtained images showing the Abu Abbas militia, which is linked to al Qaeda in the Arabian Peninsula (AQAP), patrolling in US-made MRAP armored vehicles.

Al-Malki did not deny the claim but said what was shown in media reports were damaged military vehicles being prepared for evacuation out of Yemen. He added the coalition takes seriously any claims of outside parties obtaining weapons.
