The UN Palestinian refugee agency, UNRWA, is very upset with Gazans. "They have the right to demonstrate peacefully and to protest any decision," said Mr. Abu Hasna, the agency spokesman. "But to reach that level is really unacceptable. They jumped over the walls. They stormed the gates. They began to scream and to threaten, also. What happened yesterday is crossing all the red lines." If jumping and screaming is a red line, it's a little mystifying why the crimes committed by Palestinian prisoners in Israeli jails - starting with murder - doesn't qualify for equal UNRWA umbrage.
