Yemen's Houthis just declared an ongoing war on Saudi Arabia's oil industry

Yemen's Houthis just said the Aramco attack is not a one-off.

It's the start of something longer.

Here's what happened. A few hours ago, Yahya Saree, the Houthi military spokesman, said Houthi forces hit three places at once. Saudi Aramco's headquarters in Dhahran. King Khalid International Airport in Riyadh. And an Aramco refinery, also in Riyadh.

Saree says the operation used a large number of ballistic missiles, cruise missiles and drones.

And then he said the part that matters most. He says these operations against Saudi airports and oil facilities will keep going in the coming days.

So this isn't one strike anymore. It's a campaign, and the Houthis are telling everyone that themselves.

Now, the Aramco part of this actually started the night before. A ballistic missile hit an office tower inside the Dhahran complex.

So how bad was it? Depends who you ask.

Saudi Arabia's Energy Ministry says it was a limited fire in an administrative building. No injuries, no deaths.

But a Saudi Aramco source told Reuters something different. That source says the missile damaged the top three floors of that office tower.

And there's a third account on top of those two. The Saudi-led coalition says fragments from a missile it intercepted near Dhahran fell on a residential area. It hasn't said what that damage looked like either.

Three Saudi-linked accounts. Three different pictures. None of them match up yet.

So why does Dhahran matter so much? Because of what's actually there.

That complex runs a major operations centre. It oversees Aramco's onshore and offshore oil rigs, its pipelines, its refineries, its export terminals. This sits right next to the control room of Saudi Arabia's oil industry.

Riyadh got hit too. The Saudi-led coalition says it intercepted a ballistic missile heading for the capital, and residents say they heard loud booms. Four people were hurt and 15 homes were damaged when debris from two intercepted missiles came down on residential areas.

And King Khalid International Airport, one of today's targets, has now been hit four times in under two weeks.

The worst one came four days ago. A Houthi missile killed at least 12 people and wounded more than 300. That is the deadliest attack on Saudi soil in more than a decade.
