KABUL, April 29 (Reuters) - Hundreds of Afghans, some shouting "Death to America", protested in the east on Sunday after six people were killed during a raid by U.S.-led coalition forces.

Nangahar police spokesman Abdul Ghafur said the six dead were all civilians, including three women, but the U.S. military said four of those killed were Taliban fighters and that two women civilians died in crossfire.

The military said the early Sunday morning raid had targeted a car bomb cell when its soldiers came under fire.

Angry demonstrators blocked a main road near the provincial capital, Jalalabad, with tree branches.

Some also chanted "Death to Karzai", referring to President Hamid Karzai who is seen by some Afghans as too close to his Western allies.

Several hundred civilians have died in fighting this year, most due to attacks by the Taliban, including suicide bombings, but a significant number also due to action by foreign forces.

Last month, U.S. Marines killed several civilians when they opened fire in Nangahar after their convoy was hit by a suicide car bomb.

The unit was recalled to the United States soon after and an inquiry is underway. That incident also triggered a major protest.
