U.S. federal agents are questioning Saudi students who were training at a naval air base in Pensacola, Florida, after 21-year-old Mohammed Alshamrani, a 2nd Lieutenant in the Royal Saudi Air Force, opened fire in a classroom with a Model 45 Glock handgun on Friday, killing three aviation students and wounding eight others, before being shot dead in a gunfight.
Last Friday, Mohammed Alshamrani, a 21-year-old second lieutenant in the Royal Saudi Air Force and a student naval flight officer, opened fire in a classroom building at Naval Air Station Pensacola in Florida, killing three sailors.
US Politicians have called for stricter screening of the hundreds of foreign nationals who travel to the States every year for military training.
Florida's governor, Ron DeSantis called for more stringent security measures.
Earlier, US Defense Secretary said he has ordered a review of vetting procedures while defending the training programme that brought Alshamrani to Pensacola.
But members of Congress representing Florida have blasted the US government for not already labeling the shooting as a terrorist attack and have demanded more details about what the Saudi government is doing to help the investigation and prevent future violence by members of its military.More news: Tiger skin, foetuses found in Indonesia poacher case
Speaking at a press conference on Sunday afternoon, DeSantis also said that the gunman had a trace on social media and a "deep-rooted hatred for the United States".
It has been reported in United States media that Alshamrani played mass-shooting videos to others at a dinner earlier in the week, according to an anonymous official briefed on the investigation.
The FBI team probing the shooting at a US Navy base in Florida expressed its appreciation to Saudi officials and students for their cooperation in the investigations.
Alshamrani reported that the confrontation came at the end of a meteorology class, when the instructor, James Day, asked whether students had any questions before he dismissed them.
I'm watching the same things that you're watching and the public reports and this is a guy who may very well have said some things on Twitter that suggest he was radicalized.
"And if there are Saudis that we do not have that may have been involved in any way in the planning, inspiration, financing or execution of this, that we expect Saudi intelligence to work with our government to find the people accountable and hold them responsible".More news: 'Marriage Story' tops Golden Globe Award nominations with 6
The FBI has identified Friday's shooter as Mohammed Alshamrani, 21.
Those fatally shot are identified as: Airman Mohammed Hotham of St. Petersburg, Florida; Ensign Joshua Watson of Coffee, Alabama, and Airman Apprentice Cameron Walters of Richmond Hill, Georgia.
"We are unable to confirm this type of information due to the active and ongoing investigation", Amanda Warford Videll, a spokeswoman for the bureau's Jacksonville office, said in a statement. A Saudi pilot in training kills 3 of our soldiers.
It took place across two floors of a classroom building and ended when a sheriff's deputy killed Alshamrani.
President Donald Trump's national security adviser, Robert O'Brien, said on CBS's "Face the Nation" that the shooting looked like "terrorism or similar to terrorism". The shooting left three service members dead and eight others injured. "He died a hero and we are beyond proud".
Multiple Saudi students close to the gunman are cooperating with investigators as their Saudi commanding officer restricts them to the base, Rojas said, adding that the Saudi government has also pledged full cooperation.More news: Hundreds Will Spend the Night in Sleeping Bags on Times Square
"This has been done for many decades", the president said. "I like allies. Saudi Arabia's an ally, but there's something really bad here fundamentally". We've been doing this with other foreign countries.
