Pompeo lands in Abu Dhabi to discuss attack on Saudi oil facility

The U.S. Secretary of State has described the attack as an act of war, though U.S. President Donald Trump on Wednesday (September 18) struck a cautious note.

He said there were many options short of war with Iran, which denies involvement in the Sept. 14 strikes that initially halved Saudi oil output.

Trump ordered increased sanctions on Tehran.

"This is an attack of a scale we've just not seen before," Pompeo told reporters before landing in Jeddah for talks with Crown Prince Mohammed bin Salman on Wednesday.

"The Saudis were the nation that were attacked. It was on their soil. It was an act of war against them directly."

Riyadh, which described the assault has as a "test of global will", on Wednesday displayed the remnants of 25 Iranian drones and missiles it said were used in the strike as undeniable evidence of Iranian aggression.
