Fighting continues in Baghdad as Maliki's Iraqi army (IA) battles Muqtada al Sadr's Mahdi army for control of the precinct of Iraq's capital known as Sadr City. Earlier media reports that the Mahdi army had battled the government forces to a standstill seem to have been premature since the IA seems to have the initiative everywhere it chooses to press the battle. Bill Roggio has details as does Hot Air.
Reports indicate that American forces are supporting the IA with M1A2 Abrams tanks and Predator unmanned aerial vehicles which are capable of firing hellfire missiles.
This video shows two Predator attacks. The first is on some mortar or rocket batteries from which explosives were launched that killed civilians in Baghdad. The second is against a force of about ten "criminals" (as the Iraqi government is now calling Mahdi militiamen). It's not pretty, and you shouldn't watch it if you'd rather not think about what's happening on the streets of Baghdad.
