Apparently, US troops and tanks are around one of the central palaces, presumably with the idea that if they occupy this area, they will demoralize resistance. Occupation does not necessarily equate to control, however.
Lots of chatter from reporters talking about what they're seeing. Wish they had some sound baffling on their generator so I could hear a bit better...
