Hundreds of people took to the streets of New York City Saturday for the third consecutive day of protests against recent police shootings in Louisiana and Minnesota.
The protesters chanted "Black lives matter" and "No justice, no peace" as they marched up Broadway from an area near City Hall.
Police officers on foot and on motorcycles kept the marchers on the sidewalks. However, more than a dozen protesters were arrested at Union Square.
Some of those arrested had marched to Union Square from Brooklyn to protest the death of Delrawn Small who was shot by an off-duty police officer in what is being described as a road-rage incident.
Small was shot just after midnight July 4 in the East New York section of Brooklyn. The state attorney general's office is reviewing surveillance video of the incident.
Protester Cynthia Howell said she isn't anti-police, but wants to see accountability.
Howell is a niece of Alberta Spruill, who died of a heart attack in 2003 after police threw a concussion grenade into her Harlem apartment.
Howell said officers who do "reckless, dangerous things" must be held accountable.
Earlier in the day, the Rev. Al Sharpton called the killings of five police officers in Dallas a "horrific, despicable" act during his weekly address at the National Action Network's "House of Justice" in Harlem.
But he argued that bad police officers need to be prosecuted in the deaths of innocent people.
About 200 people attended the event, including Gwen Carr, the mother of Eric Garner, who died in a police chokehold in 2014.
Sharpton is a talk-show host on MSNBC, which is owned by NBCUniversal, the parent company of this site.
On Friday night, about 300 people took to the streets to protest the recent police shootings.
One group marched across the Williamsburg Bridge into Brooklyn while another went uptown and marched through Grand Central Terminal.
The protesters were demanding justice for black men killed by officers and were still holding signs saying "Black Lives Matter." But some also held signs saying, "We mourn for Dallas too."
Forty people were arrested in Thursday's protests in New York City before news of the Dallas shootings broke.
The NYPD said Friday it had received 50 threats against officers since the fatal police shootings of Philando Castile and Alton Sterling but none of those threats have been deemed credible.
The department issued a memo requiring all officers to double up on patrols and to take their meals and breaks in pairs.
