CAIRO (AP) - Egypt's capital is descending further into chaos after five days of anti-government protests that left more than 70 people dead nationwide.

Thousands of protesters have defied a curfew for the second night, standing their ground in Cairo's main square in a rejection of President Hosni Mubarak's promises of reform and a new government.
      
Gangs of thugs are setting fires and looting shops and homes. Residents and shopkeepers in affluent neighborhoods are boarding up their houses and stores.

Tanks and armored personnel carriers have fanned out across the city, guarding key government buildings. Egyptian television says the army is deploying reinforcements to neighborhoods to try to control the lawlessness.
      
The military is protecting major tourist and archaeological sites such as the Egyptian Museum, home to some of the country's most treasured antiquities.
      
The country's antiquities chief says would-be looters broke into the museum, ripped the heads off two mummies and damaged about 10 small artifacts before being caught by soldiers.
