New York ? Cameraman Paul Douglas had spent more than a decade covering the world’s hot spots for CBS News. Freelance soundman James Brolan was part of a CBS team honored for its dispatches on the earthquake in Pakistan. Correspondent Kimberly Dozier had reported on the deteriorating situation in Iraq for nearly three years.

The two British men were killed Monday in Baghdad when a car bomb exploded as they were working on a story about American troops in Iraq on Memorial Day. Douglas, 48, and Brolan, 42, died at the scene, the network said.

Dozier, a 39-year-old American, was in critical condition at a U.S. military hospital in Baghdad and underwent two surgeries for injuries from the bombing, said Kelli Edwards, a CBS News spokeswoman. By early today, doctors had removed shrapnel from Dozier’s head but said she had more serious injuries to her lower body, CBS News reported on its Web site.

“Kimberly, Paul and James were veterans of war coverage who proved their bravery and dedication every single day,” CBS News President Sean McManus said. “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.”

Dozier’s relatives were planning to head to Germany, a man who answered the phone at her mother’s home in Maryland said Monday night. The Landstuhl Regional Medical Center in Germany is the U.S. military’s largest overseas hospital.

Douglas, a British national based in London, had worked for CBS News since the early 1990s in places including Afghanistan, Pakistan, Rwanda and Bosnia. He is survived by his wife, two daughters and three grandchildren, CBS said.

Brolan, who also was based in London, had worked with CBS News during the last year in Iraq and Afghanistan as a freelancer. The British citizen leaves behind his wife of 20 years, Geri, and two children – 18-year-old Sam and 12-year-old Agatha.
