From The Long War Journal:
The showdown with the Mahdi Army continues in Baghdad and outlying areas to the North as Iraq's prime minister says the days of the militias are over. US and Iraqi forces engaged the Mahdi Army in Baghdad and the towns of Rashidiyah and Hussaniyah in northern Baghdad Province over the past several days, killing 16 Mahdi Army fighters and capturing five. Seventy-two Mahdi Army fighters have been killed in Baghdad since Muqtada al Sadr threatened to initiate a third uprising.
Well done to the IA and the US MiTTs teams. Keep up the good work.
Update: US, Iraqi troops killed 41 Mahdi Army fighters in Baghdad clashes
