As most of you probably already know, a car bomb explosion in East Baghdad, roughly one mile from the green zone, killed two CBS News crew members yesterday as they were reporting a routine Memorial Day story. A U.S. soldier and an Iraqi interpreter were also killed during the attack. CBS correspondent Kimberly Dozier (bio here) was also severely wounded. The CBS news team was embedded with the U.S. Army's 4th Infantry Division.

Cameraman Paul Douglas and sound man James Brolan were both British citizens. Douglas had been to Iraq, Afghanistan, Pakitsan, Rwanda and Bosnia for CBS since the early 1990s and Brolan, 42, freelanced for CBS in Baghdad and Afghanistan over the past year.

Dozier underwent surgery yesterday and today at a U.S. military hospital in Baghdad and remains in critical condition.

This brings the total of slain journalists since the U.S. invasion in 2003 to 70.

ABC's Bob Woodruff, no stranger to the dangers of the job, wrote his thoughts over at The World Newser.

TVNewser has the text of a statement from the Brolan family.

Marcy McGinnis, the former senior vice president for news coverage at CBS News, also expresses her grief at Public Eye.

More thoughts from Vaughn Ververs, ABC's Dan Harris and Jim Sciutto, Dan Rather, Allen Pizzey, and NBC's Campbell Brown.

CBS News president Sean McManus called the tragedy a "devastating loss for CBS News."

"Kimberly, Paul and James were veterans of war coverage who proved their bravery and dedication every single day. They always volunteered for dangerous assignments and were invaluable in our attempt to report the news to the American public. Our deepest sympathy goes out to the families of Paul and James, and we are hoping and praying for a complete recovery by Kimberly. Countless men and women put their lives on the line, day in and day out, in Iraq and other dangerous spots around the world, and they deserve our utmost respect and gratitude for the work they do."
