Somali refugee Abdul Razak Ali Artan posted on Facebook that he was 'sick and tired of seeing my fellow Muslim brothers being killed and tortured' shortly before he went on a slashing rampage at the Ohio State University that left 11 injured.

Authorities are currently investigating the posts, allegedly made by Artan, which mention radical cleric Anwar Awlaki and accuse America of 'interfering' with other nations. 'I am sick and tired of seeing my fellow Muslim brothers and sisters being killed and tortured EVERYWHERE,' it stated. 'I can't take it anymore. 'America! Stop interfering with other countries, especially Muslim Ummah (communities)... [if] you want us Muslims to stop carrying lone wolf attacks.' 'We are not weak, remember that,' the post said, according to NBC News. Two hours before that, another post read: 'Forgive and forget. Love.'

Artan left at least 11 injured - one critically - after he drove onto the sidewalk at the university on Monday, mowing down crowds of innocent bystanders, witnesses say. He then jumped out of the car and began slashing victims with a butcher knife, according to police.
