(NBC NEWS) CAIRO – Egypt’s capital descended into a chaotic bloodbath Wednesday after security forces sent bulldozers into protest camps set up by supporters of ousted president Mohammed Morsi, sparking deadly violence.

A month-long nationwide state of emergency was declared, and a nighttime curfew imposed in some areas, as the interim government tried to restore order.

At least 149 people were killed and 1,403 injured, the country’s health ministry said, but the toll looked certain to rise as unrest spread from Cairo to other parts of the country.
