GAZA CITY (Ma'an) -- Israel has rearrested 15 Palestinians released in the October 2011 prisoner exchange with Hamas, a research center for prisoner affairs said Tuesday.

The latest detainee to be rearrested is Omar Abu Haniyeh, a 21-year-old from Qalqiliya, the head of the Prisoner Studies Center in Gaza said.

In a statement, Riyad al-Ashqar said Israel was disrespecting its agreements with Egypt, which brokered the prisoner swap in which Israeli soldier Gilad Shalit was freed.

He also criticized Israel's use of military order 1651, under which a military committee can cancel a prisoner's amnesty based on secret charges and evidence that even the detainee's lawyer is not permitted to see.
