Meanwhile, a CBS spokeswoman says a CBS Radio News correspondent was seriously injured by a bomb in Afghanistan. Cami McCormick suffered a leg wound when the Army vehicle in which she was riding struck a bomb south of Kabul on Friday.

She was treated at a field hospital, where she was in stable condition after surgery. McCormick was transported to Bagram Air Base, north of Kabul, for more treatment.

McCormick is an award-winning New York-based correspondent who has worked for CBS Radio News since 1998. The 47-year-old was covering the recent elections in Afghanistan.

At least 732 U.S. service members have died in the Afghan war since the U.S.-led invasion of late 2001. Nearly 60 percent of those deaths occurred since the Taliban insurgency began to rebound in 2007.

The latest spike in U.S. deaths has raised doubts among the United States and its allies about the course of the war, which was launched by the Bush administration after the Taliban government refused to hand over Osama bin Laden for his role in the Sept. 11, 2001, terror attacks in the United States.

A recent Washington Post-ABC News poll found that just over 50 percent of the American respondents said the war in Afghanistan was not worth fighting. Anti-war sentiment is also growing in Britain following a spike in deaths among British forces in Afghanistan.

The debate over the war is likely to accelerate when the new top commander in Afghanistan, Gen. Stanley McChrystal, submits an assessment of the conflict by the end of this month.

McChrystal, who commanded special operations troops in Iraq, is expected to give a bleak assessment of the war, pointing to deficiencies in the Afghan government and recommending vastly expanding the size of Afghanistan's own security forces.
