The Saudi coalition said there were no casualties in the widespread attack, but damage was done to vehicles and homes. The extent of the damage to the attacked oil, gas and water facilities is unknown. The pro-Iranian Shiite Houthi rebels, who rejected a proposal for peace talks in Riyadh, said they had carried out "extensive action in the depths of Saudi Arabia"

The Houthi rebels in Yemen this morning (Sunday) attacked Saudi Arabia with drones and missiles fired at a gas facility, a water purification plant, an oil facility and a power plant, the official Saudi news agency reported. But civilian vehicles and homes in the area were damaged, and she said she intercepted some of the launches, but the extent of the damage to the energy facilities is unclear so far.

This is another escalation in the destructive war, which has been going on for more than seven years, and is happening against the background of the stalemate in the peace talks between the parties. The Houthis last week rejected an invitation from the Gulf Council to hold peace talks in Riyadh, and are demanding that negotiations be held in a neutral state.

At the same time, the launches at the oil facility occurred when the state-owned oil company Aramco announced a 124% jump in its revenues last year, which totaled $110 billion. The big jump stems from the renewed fears in the world of shortages of energy supply, partly due to the war in Ukraine and the boycott of Russian oil. The price of a barrel of oil this morning hovered around $107, after earlier this month it had already soared to a high of $140.

Saudi Arabia and its ally the United Arab Emirates oppose Western pressure to increase their oil production and calm markets. It is estimated that they refuse to help the United States until it has increased its support for its war on pro-Iranian Houthis. A spokesman for the Shiite rebels said this morning that it was a "broad-based military operation in the depths of Saudi Arabia", without elaborating further.

Despite the efforts of Saudi Crown Prince Muhammad bin Salman to wean the kingdom's economy from oil, it has remained significantly dependent on oil exports to fill the government treasury.
