The unmanned aerial vehicles used in attacking the Saudi oil facilities on Saturday are Iranian-made and were not originated from Yemen, the Saudi-led coalition said Monday, refuting the Houthi claims.
Initial investigations in the attack on Aramco facilities indicate that the weapons used are Iranian, coalition spokesman told reporters in Riyadh.
UAVs were not originated from Yemen, and investigations are underway to know their origin, Turki al-Maliki added, noting that Houthis in Yemen use the Iranian-made Ababil drones.
The Houthi rebels persistently target civil areas with ballistic missiles and UAVs, he claimed, accusing the group of continually violating and obstructing the Hodeida deal reached by Yemeni rivals at Stockholm peace talks last December.
Yemen has been racked by a 4.5-year bloody conflictbetween the internationally-recognized Yemeni government's forces, backed by a Saudi-led coalition, and the Iranian-backed Houthi rebels who ousted the government in 2014.
The coalition is able to defend oil facilities in Saudi Arabia, Maliki said.
The Houthi group in Yemen has claimed responsibility for Saturday attacks on two Saudi Aramco oil facilities, nocking its production down to half.
The United States has accused Iran of the attack, a charge denied by Tehran, with reports tracing the drone launch to Iraq not Yemen, but Baghdad has also denied.
