Oil supply is back to what it was before the attack, but we don't know yet who is responsible - Saudi energy minister

Minister Prince Abdulaziz bin Salman told the media that oil production in October would reach 9.89 million barrels per day and 12 million bpd by the end of November.

He said Riyadh did not yet know who was responsible for the attacks, though Washington has pointed the finger at Tehran. 

Iran has denied involvement inthe attacks and Houthi rebels in Yemen have taken responsibility, warning that more could be forthcoming.

The attacks on refineries at Abqaiq and Khurais slashed Riyadh’s output by 50 percent and knocked out more than five percent of global daily production. Saudi Aramco CEO Amin Nasser says, however, that it is now producing “two million barrels” from Abqaiq.

Nasser said Saudi Aramco is still in the process of estimating the repair work that needs to be carried out on the refineries. He also said the kingdom's petroleum reserves were effective in coping with the crisis.new messages.

Aramco is the company "that you can trust the most in the world," he said.

Nasser also said the company is committed to a planned IPO listing and "will be ready" for it any time in the coming 12 months "as per market opportunity."

Iran's foreign minister Javad Zarif said on Tuesday that the US was "in denial" over its suggestion of Iranian involvement in the attacks on Saudi Arabia's oil facilities.

Washington is in denial “if it thinks that Yemeni victims of 4.5 yrs of the worst war crimes wouldn't do all to strike back,” he said in a tweet, adding that “blaming Iran” would not change that.
