Guardian Films looks at the war in the west, where those three chlorine bombs went off this weekend. Not hard to guess whodunnit:

Friday’s attack in Anbar province appeared to target Sheik Khamis Hasnawi al-Eifan of Albu Issa, a Sunni tribe that had moved to expel al Qaeda from its territory and work with the government. Many tribe members had joined the police force.

WashTimes says to expect this pattern to repeat itself in Diyala province in the east, which has 19 major tribes and where many of the jihadis fleeing the surge in Baghdad have escaped to.
