Clashes in Cairo as Egypt plunges deeper into crisis Police early Wednesday fired tear gas into Cairo's Tahrir Square, where several hundred protesters spent the night after a mass rally to denounce Morsi's power grab. Clashes that have been erupting on streets just off Tahrir near the US embassy spilled into the square, with canisters falling into the crowd forcing protesters to run and sending clouds of tear gas over the tents housing the demonstrators.
