Abdel Qader Yassin, Palestinian writer and thinker, has denounced the announcements of the Egyptian Interior ministry after of the attacks of Rafah, as it announced the involvement of Palestinians in the attacks which I'm pretty sure it's not true.
Yassin added that the attack was mentioned by Israel since August 2, but no action was taken aiming at causing embarrassment for the Egyptian president or to cause negative reaction from the Egyptians towards the Palestinians.
