The court appeal claimed that in light of a recent spate of deadly attacks on Israelis in the West Bank, the government should review the decision it made earlier this year to release the convicts. The Supreme Court rejected that claim and ruled that there was no legal basis to cancel the release.
An organization of bereaved families behind the appeal has said it fears the prisoners, all convicted in connection to the deaths of Israelis, will return to violence once freed.
Highlighting the opposition to the move, some 50 Israelis protested outside the West Bank prison where the inmates were held ahead of the release. They held signs reading "death to murderers" and burned keffiyehs, traditional Palestinian headscarves. Over a thousand people demonstrated against the release on Monday.
