"Almost certainly it's Iranian-backed," Prince Khalid bin Bander bin Sultan Al Saud, an ambassador to London, claimed. "We're trying not to react too quickly because the last thing we need is more conflict in the region... We're investigating the issue. We're working with our partners in the United States, the UN, the UK, and anyone else who wants to get involved, to help us resolve what happened, figure out what happened, where they came from, the attack".
According to a statement from the Houthi armed forces, broadcast by Almasirah TV channel, the group launched ten drones targeting the Abqaiq and Khurais oil refineries. The statement also said the attacks would continue until the kingdom stops its military operations in Yemen, where Saudis have been conducting strikes against militants in support of Abdrabbuh Mansur Hadi amid a civil war.
Meanwhile, Iranian Defence Minister Amir Hatami insisted that Tehran played no role in the attacks.
"Quite obviously, it was a military clash between the two countries. The Yemeni were one of the sides, they said themselves they did it" the minister said as quoted by the ISNA news agency.
The Saudi Aramco facilities were hit by drones on Saturday, resulting in a massive fire at the compounds. Saudi officials, however, stated that oil supplies would be back online soon.
