There was a news conference today in Riyadh to report on the progress in investigations by the Saudi Arabia/ UAE/ recognized Yemeni government coalition of incidents during coalition attacks in the Yemeni war resulting in civilian casualties. The only update given for the school bus attack in Saada earlier this week was that a team has been appointed to investigate. The rest of the news conference gave updates on other incidents, beginning with one that occurred on ... April 2015. The most recent land incident addressed was in September 2017, and the report concluded with the findings about the attack on three ships in Hodeidah harbour in May 2018. The conclusion in that last case was that the ships were booby trapped and a legitimate target, and in all other cases except one, the conclusion was that given the presence of Houthi forces around the incident, the attack was legitimate no matter who was killed. And in the single case of admitted error (an air-to-ground missile attack on a car), the excuse is that the error was unintentional, whatever that means.
