American hunger striker Mohamed Soltan's health plummets in Egypt

American-Egyptian hunger striker Mohamed Soltan has been shown bleeding from his mouth in a photo posted to Twitter on Tuesday.

The 27-year-old Ohio State graduate has been held by authorities in Egypt since August 2013. He has been on hunger strike since 26 January 2014.

Soltan is accused, along with 51 co-defendants, including his father and top Muslim Brotherhood leader Mohamed Badie, of forming what came to be known as the "Rabaa Operations Room" during a sit-in during 2013 in support of ousted president Mohamed Morsi.

He is being held at a prison hospital and court hearings have been postponed 25 times in his case. Authorities have refused calls for his immediate release and activists have spoken out about his deteriorating health condition.

“He has gone into two separate incidents of hypoglycaemic comas, has shown symptoms of liver and kidney failure, has haemorrhages throughout his body and there’s also a psychological component to his torture,” Masoud Nafey, a member of the Free Soltan campaign, told The Lantern student newspaper at Ohio State.

When he has been called to court Soltan has been transferred via ambulance and appeared strapped to a bed.

The only nutrients he receives are in the form of a glucose injection. His condition is critical but family members have said he will remain on hunger strike.

Soltan’s “will is still strong, he continues his hunger strike,” Nafey said. “Nonetheless, he is barely surviving. We can’t wait long.”

Despite repeated appeals to the American government to do more to secure his release, including Soltan himself sending Obama a video message from prison after 100 days of his hunger strike, his release has yet to be secured.
