After Operation Breaking Dawn, it summarized:
During the escalation, 49 Palestinians were killed in the Gaza Strip, of whom at least 22 were civilians, including 17 children and four women, according to OHCHR.
The report implies that all the Palestinians were killed by Israel, but in its statistics section showing the cumulative casualties during the year (there were no deaths in Gaza before August) it adds a footnote:
The report itself says nothing about Palestinian rockets that fell short; you need to read between the lines of the statistics to find out that the UN was still investigating how these 13 - or, if you do the math of 49-35, 14 - were killed.
So what happened to this footnote in the latest bulletin?
It disappeared, yet the number of those killed in Gaza - 35 - remained the same.
This means that between August 15 and August 29, the UN determined with certainty that 14 Palestinians - including many children - were killed by Gaza rockets.
But they never reported that fact.
Even though their entire purpose is to protect civilians, when Gaza civilians are killed by Palestinian militants, they go out of their way to not report it - and instead, their report text still implies that Israel killed them.
This isn't a mistake or an oversight. The UN consciously counted the casualties, determined that 14 were killed by Islamic Jihad and their allies, and chose not to report those civilian deaths instead of reporting to the world that Gaza terrorists kill their own people.
Sometimes, the bias can be seen in the details. And once you see it here, there is no other way to interpret the text of these two reports outside of a desire to maximize blame to Israel and minimize it for Islamic Jihad.
