CNN.com - U.S. lockdown after Afghan riot - May 29, 2006: "KABUL, Afghanistan (CNN) -- The U.S. military headquarters in Afghanistan's capital is under lockdown after angry locals took to the streets when an American truck ran into pedestrians.

One person was killed and six others were injured in Kabul on Monday when a truck in an American military convoy lost its brakes and crashed into a crowd of bystanders."

Two of those injured are in critical condition, the U.S. military said.

Some angry Afghans took to the streets after the crash, throwing rocks and overturning Afghan police cars.

One person was killed when firing broke out during the protests, Reuters reported a security official as saying.

It was not immediately clear who opened fire. A Reuters reporter at the scene saw one man shot dead and several wounded people being taken away.

Witnesses said some protesters had been killed after police intervened and forced protesters to scatter, according to Reuters.

"There are casualties, killed and wounded," said a security official who declined to be identified.

No American troops are allowed to leave the base.

The United States has 23,000 troops in Afghanistan, while a NATO-led peacekeeping force has more than 9,000 troops in the nation.
