US forces are pulling out of Karbala. I’ve only seen this article on the NY Times, and am surprised no one else is reporting on it. Relevant paragraphs:
Colonel Bishop said the withdrawal was intended to “allow time for the political process to go forward.” He declined to give details on that process, and it was not immediately clear what negotiations were taking place.
American officials have been pressuring the Shiite religious establishment to wrest a surrender from the militia’s leader, the cleric Moktada al-Sadr, but the senior clerics have so far failed to do so.
Colonel Bishop said the withdrawal of forces from the Mukhaiyam Mosque did not amount to a cease-fire. His battalion will continue to run regular patrols into the city, he said, and “will continue to respond to any attacks against Iraqi security forces.”
