Rallies, vigils after killings by police, Dallas ambush

(CNN)People across the United States are planning to come together Friday and this weekend in reaction to back-to-back police shootings caught on video this week and Thursday night's deadly shooting of five Dallas police officers.

The Dallas killings took place during a street protest over police violence. Videos showing two African-American men shot by police earlier this week in Louisiana and Minnesota spurred protests and debate over police use of force.
Here's a look at some of the planned rallies:

    Atlanta

    The Atlanta chapter of the NAACP has organized a "march for justice" at 6 p.m. Friday at Centennial Olympic Park, starting at the nearby National Center for Civil and Human Rights museum.
    The Atlanta Journal-Constitution reports a "hundred or so" protesters marched in the city's downtown Thursday night, some chanting "no justice, no peace; no racist police" in the wake of the videotaped killings of Alton Sterling in Baton Rouge, Louisiana, and Philando Castile near Minneapolis -- both at the hands of police officers.

    Austin, Texas

    The Texas governor's mansion will be lit in blue as a tribute to the five slain police officers, according to a statement from Gov. Greg Abbott.

    Baton Rouge, Louisiana

    The city's NAACP chapter was holding what it calls a "rally for justice" on Friday. Baton Rouge is where Alton Sterling was shot and killed by a police officer this week.
