The Huthi rebels claimed responsibility for attacks with drones and robots on the important oil depot set on fire in Saudi Arabia.
The time of the attack seems to have been carefully chosen, just a few miles from the oil plant, test races were run in Formula 1, in the competition that is full of prestige for Saudi Arabia.
The response from Saudi forces, which leads an armed coalition in the fight against the Iranian-backed Huthi rebels, became unusually brutal.
The capital Sanaa, which is occupied by the Huthi movement, and Hodeida on the Red Sea, were attacked in intense air raids, where government buildings and power plants were bombed.
After the attacks, the Huthi rebels came up with a proposal for a unilateral ceasefire for three days, including on Sunday when the Formula 1 race is run.
"And we are ready to make this declaration of intent a final and permanent promise in case Saudi Arabia promises to end its siege, and stop attacking Yemen once and for all," the Huthi rebels wrote in a statement on Saturday.
Saudi Arabia had not commented on the outcome late on Saturday.
The Huthi rebels captured Yemen's capital Sanaa in 2014, and the country's civil war has since worsened.
In 2015, Saudi Arabia joined the fight against the Huthi rebels.
