Jonathan Pollard, the victim of cruel and unusual punishment in the U.S. over spying for Israel, is in stable condition.

Pollard’s wife, Esther, received an update Sunday night from the U.S. prison where Pollard is being held that he is still hospitalized but his condition is now stable.

She had been informed Saturday that Jonathan was hospitalized after he collapsed in his jail cell during the weekend. His condition was initially not known.

Pollard began his 28th year in jail two weeks ago. No one else convicted of spying for a friendly nation has had to serve a sentence anywhere near as long.

He has been suffering from intense pain in the past few weeks but it is not known if his collapse is connected to the pains.
