Israel's Supreme Court has scheduled a hearing this week on the appeal of a Palestinian prisoner waging an unprecedented hunger strike that has stretched for more than two months, court officials and his lawyers said Monday.

Khader Adnan, a member of the Islamic Jihad militant group, is demanding he be released immediately. He has not been charged with a crime and does not know what he is suspected of doing.

The case of the 33-year-old Adnan has attracted widespread attention among Palestinians, with large crowds holding regular protests in his support.

The life-threatening gamble has also drawn broader attention toward Israel's policy of "administrative detention," under which Palestinians can be held without charge for months, and even years, at a time.

Both the European Union and the United Nations have said they are following the case closely and urged Israel to give Adnan an open trial.

Adnan was arrested on Dec. 17 and later sentenced to four months of administrative detention. He launched the strike a day after his arrest, protesting his administrative detention and claiming he was beaten and humiliated in captivity.
