Wanna know how the Civil War in Gaza all started? Journalist Charles Levinson lays it all out on his blog Conflict Blotter -News, Analysis and Original Reporting on the Middle East . It is extremely interesting and well worth the read:

Here is a timeline of events in the 48 hours leading up to civil war as relayed to me by a close adviser to the Commander of the now dissolved Presidential Guards:

* SATURDAY 10:30 a.m. – A family closely tied to Hamas’ armed wing the Ezzedine al Qassam Brigades sets up a checkpoint outside the Abu Jihad Al Wazir mosque on the beach road about two km south of Abbas’ compound in Gaza City. Within minutes they kidnap a Presidential Guard soldier whose brother is the bodyguard for senior Fatah official Abdel Hakim Awad.
* 11 a.m. – The joint faction committee is alerted regarding the crisis. The committee has representatives of all the Palestinian factions, all the security forces, and the Qassam Brigades, and was established for the very purpose of resolving disputes peacefully. Hamas assures the committee that they aren’t holding the kidnapped guardsman. It’s just a family dispute they say.

He also gives more information on who was executed in THAT video.

Seriously interesting stuff.
