Cameraman Paul Douglas and soundman James Brolan died when a car bomb hit the US military unit they were accompanying in the Iraqi capital.

But doctors say she has other serious injuries to her lower body.
The CBS team was accompanying soldiers of the 4th Infantry Division. A US army officer and an Iraqi interpreter died in the same attack

- Another bomb in Adhamiya, near Baghdad's main Sunni mosque, kills at least five civilians and wounds seven
- Eleven die and 16 are injured in an explosion on a bus in Khalis, 80km (50 miles) north of Baghdad, close to a base of the Iranian opposition movement Mujahideen e-Khalq
- Seven people are killed when a minivan explodes near a street market in Baghdad
- A gun attack in Baghdad leaves two police officers dead
The CBS team were outside their armoured Humvee jeep when the bomb went off.
"It wasn't a roadside bomb it was a car bomb," Aliah Git, the executive editor of CBS Radio News, told the BBC.
"All we're being told is that they'd been stopped, the convoy, and gotten out of their vehicle due to something described only as a curious incident.
"They were wearing protective gear and a nearby car exploded."
The trio had been reporting a "routine" story, covering American troops for Memorial Day in the US, the network said.
The three were "seasoned reporters and newspeople" who had been "in and out of Baghdad probably dozens of times", Ms Git said.
The crew were reporting on US troops for Memorial Day, CBS said
Paul Douglas, 48, was a veteran of numerous war zones, including Afghanistan and Bosnia, and had been working for CBS since the early 1990s.
James Brolan, 42, was a freelancer who had been working for CBS in Afghanistan and Iraq during the last year.
Kimberly Dozier, 39, who holds dual US-British citizenship, has been reporting on the war in Iraq for nearly three years.

Iraq is considered the most dangerous country in the world for journalists.
Nearly 100 journalists have been killed in the country since the start of the 2003 US-led invasion. The latest deaths bring to 20 the number who have died in 2006.
