It was published in a number of Arabic sites, including Palestine Today.
His death was not mentioned by PCHR.
Today, Palestine Today celebrates the young man, who actually was 24 years old:
Islamic Jihad claims that Muheisen led a team that ambushed elite Israeli soldiers, killing several. That is not true, since the first Israeli casualty was on July 15.
The Meir Amit Terrorism Center so far has identified 354 terrorists, 49%, out of 751 Gaza dead that they identified positively. They note that many of the terrorists killed were not listed in various NGO reports, so when PCHR was claiming a high percentage of civilians killed, one reason it was exaggerated was because they ignored some people they knew were terrorists.
