The evacuation of New Orleans citizens stranded in the Superdome since Hurricane Katrina struck has been halted since shots were fired from the stadium at a military helicopter.
The head of Acadian Ambulance who are controlling the evacuation said that "a thousand" military police officers would be needed to bring the situation under control. All flights in and out of the Superdome have been suspended.
People with guns prevented a helicopter from landing at a hospital in the nearby town of Kenner. The New Orleans Mayor has had to divert almost all troops from search and rescue efforts to combat the increasingly hostile situation in the city.
