Mohammed Saeed Alshamrani, the Saudi national who opened fire at Naval Air Station Pensacola Friday killing three and injuring seven before being gunned down by police, hosted a dinner party days before the attack to watch videos of mass shootings, a U.S. official said.
The official, speaking on condition of anonymity, said that one of the Saudis who attended the dinner party videoed the Friday shooting, and two others watched from a car. He said 10 Saudi students are being held at the base, and that several others are still unaccounted for.
It had previously been reported that three of the Saudis in custody had been seen videoing the entire shooting.
Alshamrani posted an anti-America screed on Twitter before launching his attack.
