WASHINGTON 

US has been rocked by nationwide protests with demonstrators calling for an end to police brutality against blacks after video of an unarmed man being killed by police appeared on social media last Monday. 

During protests, demonstrators chanted "Black Lives Matter," "No Justice, No Peace," and "I can't breathe," after George Floyd died at the hands of police violence in Minneapolis, Minnesota.

Floyd's death has strong parallels to Eric Garner, who died during a 2014 arrest in New York. Garner also repeatedly pleaded with officers: "I can't breathe."

The phrase becomes a rallying point for protesters demonstrating against the killings of unarmed black men and women by police. It has continued to resonate nearly six years later.
