Protesters hold placards and shout slogans while marching on December 6, 2014 in Hollywood, California

New Yorkers took to the streets Saturday in further protests to denounce a spate of killings of unarmed black men by white police officers as relatives buried a 28-year-old father of one.

And Rev. Al Sharpton at National Action Network in Harlem announced a plan to organise a demonstration to the US capital of Washington D.C. on 13 December.

Despite heavy rain, dozens of demonstrators gathered in Times Square and later in Union Square, where the crowd huddled under umbrellas and shouted “I can’t breathe” egged on by cries of “louder, louder.”

“I can’t breathe” were the final words gasped repeatedly by Eric Garner, a 43-year-old father of six who died in July after a police chokehold that was caught on amateur video footage.

A coroner’s report ruled Garner’s death a “homicide” after police held him in a chokehold.

A grand jury’s decision on Wednesday not to indict the white officer responsible has now triggered four consecutive nights of protests in New York and other major cities across the United States, mobilizing thousands.

Another protest was scheduled later in the evening in Brooklyn.

There were also small rallies held in the US cities of Atlanta, Dallas, Houston and Tampa Bay.

In the morning, civil rights activist Al Sharpton’s National Action Network held an event in Harlem attended by actor Spike Lee.

On Friday, demonstrators staged “die-ins,” by lying on the ground at Columbia University, Grand Central Station and after pouring into Macy’s flagship store in Herald Square and the Apple store on Fifth Avenue.

Another grand jury decision not to prosecute the white officer who shot dead unarmed 18-year-old Michael Brown in Ferguson, Missouri, on August 9 also triggered riots as well as peaceful protests.

Friends and relatives on Saturday attended the funeral of Akai Gurley, who was shot dead when a police officer opened fire in a dark staircase at a Brooklyn apartment building as he walked with his girlfriend late on November 20.

Dozens of mourners paid their respects at the Brown Memorial Baptist Church, where Gurley’s gray coffin was covered in a huge spray of red and white flowers.

The 28-year-old, whose mother lived in Florida, had been planning a surprise Thanksgiving trip to introduce her to his young daughter when he was killed.
