Unrest over killing of handcuffed black man continues in USA

Tens of thousands of protesters took to the streets across America again Sunday, with peaceful demonstrations against police killings of black people overshadowed by unrest that quickly ravaged parts of cities from Pennsylvania to California.

City and state officials had deployed thousands of National Guard soldiers, enacted strict curfews and shut down mass transit systems, but that did little to stop many cities from again erupting into unrest.
