From today's New York Times:
Ann Cooper, executive director for the Committee to Protect Journalists [link added], said that 36 journalists, plus 18 translators who worked for journalists, had been killed in Iraq since 2003. Of those 54, she said, at least nine died as a result of American fire.
"From our standpoint, journalists are not being targeted by the U.S. military in Iraq," Ms. Cooper said. "But there certainly are cases where an atmosphere of what, at best, you can call indifference has led to deaths and other problems for journalists."
As an example, Ms. Cooper cited the shelling by American troops of the Palestine Hotel in Baghdad, well known as the residence of journalists, in April 2003, killing two journalists.
