JERUSALEM — Israel’s Supreme Court will hear the case of a Palestinian prisoner who has been on a hunger strike for more than 60 days.

The Supreme Court will hear the case of Khader Adnan, who was arrested on Dec. 17 on the basis of “secret evidence” that he is a threat to regional security, at noon on Thursday. A military court judge last week denied Adnan’s appeal to be released or have his detention reduced.

Adnan, 33, has been held in administrative detention without charge and has undertaken a hunger strike to protest his detention without charge, as well as humiliating treatment in prison, according to reports. He can be held in administrative detention, without charges being brought, for four months. The administrative detention went into effect on Jan. 8.

He reportedly is a member of Islamic Jihad.

He is too weak to stand up on his own, though he is shackled to a hospital bed. Doctors have warned Israeli officials that he may die soon, according to reports. He is taking liquid infusions of salts, glucose and minerals.
