If the killings in Jerusalem are revenge attacks then expect more either way. The policies being followed ensure that they will get bigger and bloodier. Already there are reports of more deaths in Gaza and at the moment an ongoing invasion of Bethlehem.
The above gives reports of the attack on a school on Jerusalem killing 8 students in the Jerusalem Post and the Palestinian News Network.

I spoke to the family of a man who had blown himself up on a bus in Jerusalem that same day. They were unaware of his intentions and had not only lost a son, but the only breadwinner in a large family. Who are the winners in this? Politicians will use the misery and suffering for their own purposes to justify their unjustifiable policies and actions past, present and future.
