On Sunday, having previously hit Saudi oil infrastructure from Ras Tanura in the east to Yanbu in the west, Houthi forces took an opportunity to strike at the headquarters building of Saudi Aramco in Riyadh. An unknown munition launched by Houthi forces hit the skyscraper in the middle, damaging several floors.

The attack occurred during the morning rush hour on Sunday, the start of the Saudi workweek. Luckily, no one was reported injured or killed, according to the Saudi energy ministry.

Bystander imagery and locally-based reporters indicate that the munition created a hole in the side of the building, with blackened edges indicative of a blast. Several explosions had been heard throughout the morning.

The energy ministry indicated in a statement that "falling shrapnel . . . caused minor damage to the building."

Over the course of the weekend, more than 50 people were killed in two airstrikes in Houthi territory. The Saudi Air Force provides air support for the internationally recognized government of Yemen, which is fighting to repel a Houthi attempt to seize Taiz and Aden. Saudi Arabia does not always claim or acknowledge airstrikes within Yemen, and has not confirmed any involvement in the attacks over the weekend. In one of the two attacks, a strike on a market near Taiz, local IRG authorities claimed that the Houthis were responsible.

Houthi forces have caused mass casualties in attacks on civilian targets within Saudi Arabia. At least 13 people died and more than 300 were injured in a missile strike on the King Khalid International Airport in Riyadh last month.
