The Palestinian Authority's prisoners affairs minister Issa Qaraqe said Monday that detainees in Israeli prisons are planning a comprehensive hunger strike on Thursday. In a statement received by the ministry, prisoners said that Thursday will be a "day of anger" to protest against Israeli negligence and mistreatment of detainees, above all Khader Adnan. The prisoners said they had called for Adnan's release and hold Israeli prison authorities responsible for his health. The Israeli Supreme Court is set to hear a petition on Thursday against the continued administrative detention of Adnan, the prisoners society said last week. He has refused food since his Dec. 17 detention in northern West Bank city of Jenin. It is the longest hunger strike any Palestinian prisoner has undertaken. There are an estimated 307 Palestinians in Israeli administrative detention -- held without charge -- in Israeli jails.
