CBS News correspondent Kimberly Dozier, who was critically wounded by a car bomb in Iraq last week, began her trip back to the United States on Wednesday after treatment at a U.S. military hospital in Germany, the Air Force said.

Dozier, 39, was wounded May 29 in a blast that killed her camera crew — Paul Douglas and James Brolan, both of Britain — as well as a U.S. soldier and an Iraqi translator.

She was flown the following day to Landstuhl Regional Medical Center in Germany for treatment of head and lower body injuries. Her family said she would need rods in her legs.

Dozier arrived Wednesday at Ramstein Air Base in a military ambulance and was wheeled onto a C-17 aircraft configured for medical evacuations in a stretcher.

She was one of about 40 patients being flown to Andrews Air Force Base in Maryland, said Air Force Capt. Chrystal Smith.

On her arrival back in the United States, Dozier was expected to be brought to the National Naval Medical Center in Bethesda, Md.
