American troops shoot and kill pregnant woman at checkpoint.

Two Iraqi women were shot to death north of Baghdad after coalition forces fired on a vehicle that failed to stop at an observation post, the U.S. military said Wednesday. Iraqi police and relatives said one of the women was about to give birth.

A car entered a clearly marked prohibited area near coalition troops at an observation post but failed to stop despite repeated visual and auditory warnings, the U.S. military said in a statement e-mailed to The Associated Press.

“Shots were fired to disable the vehicle,” the statement said. “Coalition forces later received reports from Iraqi police that two women had died from gunshot wounds ... and one of the females may have been pregnant.”

The statement said the incident was being investigated.

“The loss of life is regrettable and coalition forces go to great lengths to prevent them,” the military said.

The statement was issued after Iraqi police said a pregnant woman and her cousin were killed by American troops while driving to a maternity hospital in Samarra, a predominantly Sunni city 60 miles north of Baghdad.

The bad news is getting worse and worse as the weeks go on.
