A U.S. colonel serving in the American-led coalition in Syria on Sunday spread pro-Kurdistan Workers’ Party (PKK) propaganda on Twitter.

U.S. Colonel Sean Ryan shared a scandalous tweet on his official Twitter account calling Turkish soldiers “terrorists.”

The tweet was later removed after the colonel came under fire from social media users who were outraged by the fact that a high-ranking U.S. military official would spread anti-Turkey propaganda.

German journalist was blocked

Colonel Ryan even went as far as blocking German journalist Julian Röpcke who criticized him for retweeting the PKK propaganda, which landed the U.S. military official in more hot water.

The move prompted the journalist in a tweet to ask when it became okay to block journalists for doing their job.

Ryan was again forced to backtrack, unblocking Röpcke on Twitter.

Colonel Ryan’s outrageous retweet comes as the U.S. provides protection for PKK/PYD terrorists digging tunnels on Turkey’s southern borders.
