Authorities are investigating an anti-U.S. rant posted on Facebook just minutes before the Ohio State University attack today that is believed to be linked to suspect Abdul Razak Ali Artan, sources told ABC News.

Appearing three minutes before the beginning of the rampage that left 11 people injured, the post reads: “I can’t take it anymore. America! Stop interfering with other countries, especially the Muslim Ummah. We are not weak. We are not weak, remember that.”

The post also invokes the name Anwar Al-Awlaki , a radical American-born al-Qaeda cleric, describing him as a “hero.” Al-Awlaki was killed in 2011 but his propaganda has been linked to several domestic terrorist attacks in the years after his death.

“If you want us Muslims to stop carrying lone wolf attacks, then make peace,” the post reads. “We will not let you sleep unless you give peace to the Muslims.”

The post, which was on a page that appears to have since been disabled, takes the form of a photo of a computer screen displaying a text document.

Authorities identified Artan as the attacker in a press conference this afternoon, but said they have not determined a motive and the investigation is ongoing. Sources told ABC News that he is a of Somali descent and is a legal permanent resident in the United States.
