Saudi says oil output to be restored by end of September

Saudi Arabia said on Tuesday its oil output would be back to normal by the end of the month, with half the production lost in weekend attacks on two key facilities already restored.

Energy Minister Prince Abdulaziz bin Salman, who was only appointed to the role earlier this month, said that the world's top energy exporter had dipped into its strategic reserves to maintain supply to clients.

"I have good news for you... the oil output to international markets is back to what it was before the attack," he said.

"During the past two days the damage was contained and 50 percent of the production has been recovered," he added.

"Production will be back to normal by the end of September."
