Reply #45: let me speculate

though i have limited knowledge of qalqilia and not much time right now to ask my "sources" ill pose this question... perhaps the local al-aqsa chapter was working out of the YMCA... given the fact the YMCA was started in 2000 this might be a possibility.
perhaps the extremists of hamas or islamic jihad have some beef with the al-aqsa boys (only they know) and this was an attack or retaliation for something we dont know about.

given the fact qalqilia is completely walled in by israels wall, anything is possible. theres no economy and restricted travel. a sort of scenario where you put some folks in isolation and wait for them to get crazy enough to kill each other... you ever see that twilight zone episode?
