CAIRO — As three Egyptian cities defied President Mohammed Morsi’s attempt to quell the anarchy spreading through their streets, the nation’s top general warned Tuesday that the state itself was in danger of collapse if the feuding civilian leaders could not agree on a solution to restore order.

Thousands of residents poured into the streets of the three cities, protesting a 9 p.m. curfew with another night of chants against Morsi and assaults on the police.
