Egypt's 'unprecedented' protests

Thousands of demonstrators have taken part in major rallies across several Egyptian cities, including Cairo, the capital. Observers have called the protests the largest in years, possibly since the infamous bread riots of the 1970s.

Four people were killed on Tuesday, including a police officer, as sporadic clashes with security officers lasted into early Wednesday morning. By the pre-dawn hours, Cairo's central Tahrir Square had been turned into a "battlefield."
