Images of journalists showed the devastation of Saturday's attacks on Saudi Aramco sites in Abqaiq and Khurais in eastern Saudi Arabia.

The pictures show journalists visiting the site of Khurais, where some of the facilities showed the effects of fire and destruction, as well as the ongoing repair work at the company's target plant.

Aramco said the attack on the Khurais facility targeted four crude oil production plants.

In Khurais, technical specialists are working to estimate the enormous damage to a metal tower used to remove dissolved gas and hydrogen sulfide from oil.

Fahd Abdul Karim, a Saudi Aramco official, said during the attack, which halved oil production in the kingdom and raised prices, "there were between 200 and 300 people inside the facility."

"There were four strikes and explosions," said Abdel-Karim, who toured with reporters inside the site. "There were no fires."

An emergency team has been set up to repair the plant, relaunch activities and restore production to normal, Abdel Karim said.

"In less than 24 hours, 30 percent of the plant has returned to work," he said, adding that "production will be at the level it was before the attack by the end of the month." "We will be back stronger than before," he said.

According to the Saudi authorities, at least 18 drones and seven cruise missiles were used in these Houthi attacks, while Riyadh points the finger at Iran for the attacks.
