Update (2/16/10 11:40 a.m.): The New York Times, quoting a NATO spokesman, says today that fighting in Marja has slowed to "sporadic" gun battles with the Taliban, and that coalition forces have not suffered any more deaths after a U.S. Marine and a British soldier were killed on Saturday, the first day of the offensive.
The Los Angeles Times' Tony Perry and Laura King, reporting from Kabul and Marja, report that Marines were "inching their way forward" on Monday, sometimes through knee-deep muck, as teams painstakingly cleared IEDs. Perry and King say that some 5,000 residents of Marja have fled town. Marja is an agricultural township with an estimated population of somewhere around 80,000.
There have been contradictory reports about the artillery fire that killed 12 civilians on Sunday in Marja. Initial accounts, including from the New York Times' C.J. Chivers, who was on the scene, said that at least one rocket fired from a base dozens of miles to the north hit a house around 300 yards away from the intended target.
But Wired's Noah Schactman says that NATO is now saying those rockets hit their intended target and that troops didn't know there were civilians inside the house.
Afghan officials said three people in the house were Taliban militants firing on American troops, but Chivers reports in today's Times story that the Marines he was with "complained to an embedded New York Times reporter that they had not ordered the rocket strike and that it hit the wrong house."
