A group of Gaza students with scholarships to study in America were prevented from leaving the Gaza Strip. This is part of a larger effort by the governing authority to crack down on academic freedom and independent civil society in the Palestinian territories, and just another minor indignity and human rights violation Palestinian children must endure ....
Oh, wait -- it was Hamas' decision. Well, never mind.
(But, to be clear, the part about it being one piece of a larger effort to crackdown on independent civil society is absolutely true. Hamas has recently taken several steps to tighten its grip on all aspects of life in the Gaza Strip, with independent NGOs and aid groups being the primary targets).
UPDATE: Speak of the devil, Hamas also has been notably sanguine about Syria's shelling of Palestinian civilians in refugee camps as part of the anti-uprising crackdown.
