The mysteries surrounding last week's killing of Libyan rebel military commander ‘Abdel-Fattah Younis have not dissipated, but it increasingly seems clear that tribal and perhaps other issues were involved more than Qadhafi-Anti-Qadhafi issues. Yesterday's New York Times article offers an update, but apparently the rebels are still officially blaming "pro-Qadhafi" elements, while there's a BBC report claiming an Islamist militia is behind it. Is everything clear to you now? Thanks for clearing that up.
Personally, I think it was a gunman on the Grassy Knoll.
