Eep! The US is beginning a 'major operation' in Kirkuk. Not the kind of place you want Americans blindly wading in.
In Kirkuk, a volatile mixed city in the north, Iraqi and U.S.-led forces launched a major security operation, dubbed "the key to peace," to root out members of al-Qaeda and other Sunni Arab insurgent groups. Authorities imposed a 6 p.m. curfew and announced the detention of 155 suspected insurgents. (Washington Post)
I hope they know what they're doing; in particular I'd be worrying about the background of the Iraqi troops, the demographics of who they're arresting, and generally how much they're shaking things up :(
