1. Saudi Arabia and the U.S. edged toward blaming Iran for the weekend attack on Saudi oil facilities — but didn’t go all the way.

The Saudis said that Iranian weapons had been used. They also said the strikes had not been launched from Yemen, home of the Houthi rebels who claimed responsibility for what they said were drone strikes.

The U.S. said cruise missiles might have been involved, and President Trump said the possibility of Iranian involvement was being assessed. The Houthis have threatened more drone attacks. Iran has denied responsibility.
