Relief workers confront 'urban warfare'
Violence disrupts evacuation, rescue efforts in New Orleans
NEW ORLEANS, Louisiana (CNN) -- Violence disrupted relief efforts Thursday in New Orleans as authorities rescued desperate residents still trapped in the flooded city and tried to evacuate thousands of others living among corpses and human waste.
Federal Emergency Management Agency Director Michael Brown said his agency was attempting to work "under conditions of urban warfare."
Police snipers were stationed on the roof of their precinct, trying to protect it from armed miscreants roaming seemingly at will.
Officers warned a CNN crew to stay off the streets because of escalating danger, and cautioned others about attempted shootings and rapes by groups of young men.
