Two members of a CBS News crew were killed Monday and correspondent Kimberly Dozier was seriously wounded when a roadside bomb ripped through the U.S. military convoy in which they were traveling.
CBS identified those killed as cameraman Paul Douglas, 48, who was based in London, and sound tech James Brolan, 42.
The U.S. military has not confirmed any casualties in the powerful bomb, which destroyed a U.S. military Humvee as the convoy passed through Tahariya Square, just across the river from the Green Zone, around 11 a.m. Monday (3 a.m. ET).
The CBS employees were among at least 46 people killed in insurgent attacks in Iraq on Monday.
The CBS team -- which was embedded with the 4th Brigade Combat Team, 4th Infantry Division -- was reporting from outside their Humvee and they were believed to have been wearing protective gear when the blast went off, according to CBS.
Dozier, 39, sustained serious injuries and underwent surgery at a U.S. military hospital in Baghdad.
She is in critical condition, but doctors are cautiously optimistic about her prognosis, the network said.
Douglas had risked his life covering international conflicts for CBS since the early 1990s, including Iraq, Afghanistan, Pakistan, Rwanda and Bosnia, according to CBS News.
Brolan was a freelancer who worked with CBS News in Baghdad and Afghanistan in the past year. He also shared an award with the network for its coverage of last year's deadly earthquake in Pakistan.
Dozier has reported from Baghdad since 2003. She is based in Jerusalem.
Speaking on CNN's "Reliable Sources" in November 2004, Dozier described the dangers of trying to talk to ordinary Iraqis in Baghdad.
"The last time I tried to do that, to go to someone's home and sit down with that man and say, 'Are you thinking about leaving Iraq or staying?' the moment he saw me, blonde hair and my two armored vehicles ... he turned white," Dozier said.
"It means I can't go out and hunt a story. I'm having to wait for it to come to me, or I'm having to train Iraqi translators to go out and be my eyes, be my ears, ask the questions that I would ask if I could."
Earlier this year, ABC News anchor Bob Woodruff and cameraman Doug Vogt were seriously wounded when the U.S.-Iraqi military convoy in which they were embedded was hit by a roadside bomb near Taji, north of Baghdad.
Between 94 and 120 journalists and media support staff -- including drivers and translators -- have been killed in Iraq since the war began in 2003, according to journalists' organizations and watchdog groups.
