The highly respected human rights NGO, Adalah (meaning justice) dedicated to securing human rights for Palestinians living in Israel, has issued an urgent appeal on behalf of a reported 125 Palestinian prisoners who are engaged in a hunger strike protesting their being held in Israeli jails on the basis of ‘administrative detention’ procedures. It is the longest collective hunger strike in Palestinian history. Administrative detention is an objectionable practice by which individuals are held in prison, sometime for months or even years, without being informed of charges or facing trial. According to international law reliance on administrative detention is regarded as prohibited unless there are overwhelming reasons in the form of imminent and severe security threats to justify the failure to produce criminal charges and hold a trial. Israel has made no such appeal, and appears to use administrative detention procedures routinely and against individuals who cannot be considered security threats.
