Pompeo heading to Saudi Arabia to "coordinate" response to Saudi oil attack

A team of U.S. military forensics specialists is already on the ground to gather evidence from the sites of the attacks, Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, told reporters traveling with him in London.

The U.S. is gathering “compelling forensic evidence” from the debris of the cruise missiles and drones at the two oil facilities attacked this weekend, said a U.S. official. That evidence “will provide a compelling case of where they came from,” the official said.

Another U.S. official said there was enough information to show that the cruise missiles and drones were launched from southwestern Iran.
