Thousands of Palestinians are in Israeli jails. But one case in particular — that of Khader Adnan, a member of the radical Islamic Jihad group — has been raising tensions between the two sides.

Israel's Justice Ministry agreed Tuesday to free Adnan, who has been on a hunger strike for more than two months and was apparently near death.

Adnan's case has focused international attention on the Israeli practice of administrative detention, or detention without trial. It allows Israel to hold individuals for six months at a time without formally charging them or revealing evidence against them.
