Prisoners held without charge boycott Israeli courts

In a joint statement announcing Thursday's move, 450 people jailed under Israel's controversial practice of administrative detention said their decision had been taken "collectively and unanimously".

"The core of resisting administrative detention policy comes from boycotting this Israeli legal system," the detainees, held in various locations, said in the statement.

"We put our faith and trust in our people, their power and institutions, and in the civil society which will not leave us alone in this fight."

The prisoners also urged the Palestinian Authority to take the issue of administrative detention to the International Criminal Court (ICC) "as soon as possible".
