How many Gaza civilians were killed by Hamas rockets?

Palestine Press Agency reports that the house of Ibrahim Naji Sumairi was damaged by a Qassam rocket that fell short in the southern Gaza town of Qarara, and that his family was saved from a "certain death" by sheer luck. The rocket sprayed shrapnel all around the home.

Which brings up a question that the PCHR and B'Tselem and Goldstone did not try to answer: How many of the civilians killed in Gaza were actually killed by fire from Palestinian Arab armed groups? In the days before Cast Lead, two girls were killed in Gaza, and others were injured in separate rocket attacks.

These were not isolated incidents. In fact, in the month before Cast Lead began about 6% of the rockets fired landed in Gaza itself. During Cast Lead, some 800 Qassams were fired towards Israel, and the percentage that landed in Gaza itself is unknown, but we can safely assume that the number would have been even greater than 6% as the people launching the rockets were in a greater hurry than usual.

This indicates that between 40 and 50 rockets meant for Israel may have landed in Gaza itself, maybe more.

Every civilian killed by these rockets were counted as casualties of Israeli fire.

This does not include any civilians killed by Hamas and Islamic Jihad bullets, mortars or anti-tank missiles that were meant for the "Zionist enemy." Nor does it include those killed by secondary explosions from weapons caches purposefully placed in civilian areas.

No "human rights" organization cares enough to do the research and find out the details, though. It is much easier just to attribute all of these deaths to Israel and wash their hands of the issue.

This is what happens when truth is less important than furthering an agenda.
