Egypt’s military has deployed on the streets of Cairo to enforce a night-time curfew as the sun set on a day of rioting and violent chaos that was a major escalation in the challenge to authoritarian President Hosni Mubarak’s 30-year rule.

Egyptian protesters defied a curfew tonight as the army deployed on the streets of Cairo for the first time in four days of anti-government demonstrations.
