Saudi defense is moving to uncover information and display Iranian weapons in Aramco attacks
Saudi Arabia's Defense Ministry is to announce the results of its investigation and provide information on the attacks on Aramco's facilities on Saturday.
US Secretary of State Mike Pompeo heads to Saudi Arabia and the United Arab Emirates to "discuss" the US response to the attacks.
Washington has repeatedly accused Iran of being responsible for the attacks and officials said they were carried out from southwestern Iran and used passing missiles and drones.
Saudi state television said a defense ministry spokesman would hold a news conference in the coming hours to provide information
It said the conference would provide evidence of Iran's involvement in the attacks on Aramco and showcase the Iranian weapons used in the attacks.
A US official told Reuters on Tuesday, who spoke of the attack regimes, was confident that Riyadh's collection of material in the aftermath of the attacks would produce "overwhelming forensic evidence ... that would show where the attack came from."
Pompeo will meet Saudi Crown Prince Mohammed bin Salman in Jeddah on Wednesday before moving to Abu Dhabi to meet Crown Prince Mohammed bin Zayed, the State Department said in a statement.
Saudi Energy Minister Prince Abdulaziz bin Salman spoke on Tuesday night and spoke of "the return of oil supplies to what they were before 3: 43 minutes ... on Saturday," adding that the national oil giant Aramco rose "like a phoenix from the ashes" after the attack.
British Prime Minister Boris Johnson told Saudi Crown Prince Mohammed bin Salman on Tuesday that there must be a collective response to the attack. He also expressed "UK condemnation of the attacks and said it stands with Saudi Arabia and is committed to its security."
It was confirmed that the US intelligence services have the ability to determine where the rockets were fired.
