Naval Air Station shooter wrote anti-American and anti-Israeli tweets before rampage: report

The Saudi national who opened fire in a classroom at a naval air station in Florida Friday morning, killing three before being shot dead by officers, wrote anti-American and anti-Israeli tweets before the rampage, reports say.

Mohammed Saeed Alshamrani, who was said to be a second lieutenant in a flight training program for foreign military personnel at Naval Air Station Pensacola, posted a short manifesto to Twitter, AFP reported, citing the SITE Intelligence Group, a group that monitors jihadist media.
