Saudi Arabia's King Salman condemned a gun attack at a US naval base by a Saudi student as "barbaric", President Donald Trump said. He tweeted that the monarch had called him to offer "sincere condolences". The gunman, an aviation student, killed three people and injured at least eight at the base in Pensacola, Florida, before being shot dead. Florida Governor Ron DeSantis said the Saudi government was "going to owe a debt" to the victims. The attacker has been named by US media as Mohammed Saeed Alshamrani. He used a handgun during the shooting.
