(Compass) – An Egyptian convert to Christianity is being held in a Cairo mental hospital, where supervising doctors have told him he will stay until he recants his faith and returns to Islam. Gaser Mohammed Mahmoud, 30, was committed to the El-Khanka Hospital in early January by his adoptive parents after they learned he had become a Christian two years earlier. The hospital medical committee placed Mahmoud under the care of a female physician identified only as Dr. Nevine, whom sources describe as a fanatic Muslim. Since his forced confinement, Mahmoud has reportedly endured beatings, whippings and potentially fatal injections. El-Khanka Hospital earned international notoriety in 1997, when an escaped patient claimed he had bribed his way out of the institution to launch a terrorist attack in Cairo that killed nine German tourists.
