SITE, a private organization that monitors and tracks extremist groups’ online presence, published the text of the manifesto on Friday. While officials have yet to name the attacker, he was confirmed to be a Saudi military officer stationed at the Naval Air Station for training. Posted on Twitter shortly before the gunman carried out the shooting, the manifesto attacks what it calls an American “war of attrition” waged on Muslims around the world, citing the US drone war and the Guantanamo Bay prison in Cuba, where a number of terrorism suspects face indefinite detention.

“I’m not against you for just being American, I don’t hate you because your freedoms,” the post begins. “I hate you because every day you [support] funding and committing crimes not only against Muslims but also humanity," the manifesto, attributed to the attacker, says.

Earlier on Friday, Fox News identified the shooter as Mohammed Saeed Alshamrani, citing anonymous officials, corroborating what conservative outlet One America News reported previously. President Trump appeared to confirm the report, sharing a screenshot on Twitter.

Little else is known about the attacker, with both American and Saudi officials remaining tight-lipped about his identity or possible motives.

The manifesto was released just as the New York Times reported that six Saudi nationals had been detained for questioning at the Pensacola naval base, some of which reportedly filmed the officer’s shooting rampage, which injured eight in addition to to the fatalities.
