ABC's Woodruff, Vogt "in stable condition"

ABC World News Tonight anchor Bob Woodruff and cameraman Doug Vogt have been upgraded to "stable condition" after undergoing surgery at a US military hospital in Iraq today.

The convoy in which the two men were travelling was attacked this morning with an improvised explosive device. Both Woodruff and Vogt sustained head injuries and received emergency medical care first in Baghdad's so-called "Green Zone" before being transferred to a US military hospital in Balad, approximately 50 miles north of the Iraqi capital, according to ABC News.

"We take this as good news, but the next few days will be critical," said ABC News president David Westin in a statement. "The military plans to evacuate them to their medical facilities in Landstuhl, probably overnight tonight."
