U.S. Embassy locked down amid violent protests

Protesters set fire to a compound that houses foreign contract workers in the Afghan capital Wednesday, one of several scenes where anger erupted into violence again following Tuesday's admission by the U.S. military that Qurans had been burned as trash at the Bagram air base.

Police fired live rounds into crowds of demonstrators when they charged police lines in Kabul and other cities, leaving at least three people dead and dozens more wounded.

A U.S. military source tells CBS News demonstrators set fire to six fuel trucks outside Camp Fenty, a U.S. base near Jalalabad.

The military is struggling to get vital water supplies into the Bagram air base, meanwhile, as the backlash over the burning of Qurans at the base shows no sign of slowing down.

Thousands of protesters shouted "Death to America," and death to Afghan president Hamid Karzai.

The U.S. Embassy in Kabul suspended all unnecessary travel for its staff and urged U.S. Citizens to avoid areas where Westerners congregate, putting the Embassy on effective lockdown.

The violence began yesterday after Afghan workers found charred copies of the Koran while collecting trash outside the Bagram air base.

U.S. officials have warned that the demonstrations could continue for days.
