Cairo protesters dug in for a long fight on Monday, pressing their demand for an overhaul of the political system and the resignation of President Hosni Mubarak as many Egyptians tried to resume their normal lives. Up to 2,000 people bedded down overnight under blankets and tents made from plastic sheeting in Tahrir Square. Some slept while others camped out on woollen blankets as national and revolutionary songs blared out from loudspeakers. REUTERS/Dylan Martinez (EGYPT - Tags: POLITICS CIVIL UNREST)
