Beyonce pens open letter on Alton Sterling, Philando Castile deaths: 'Stop Killing us'

Beyonce has added her voice to the many speaking out against the recent deaths of Alton Sterling and Philando Castile, releasing a powerful statement on her website urging others to take a stand.

"We are sick and tired of the killings of young men and women in our communities," begins the statement released Thursday on Beyonce's website. "It is up to us to take a stand and demand that they 'stop killing us.'"

The deaths of both Sterling and Castile have launched a series of protests, fueling the fire of the ongoing debate of the police's treatment of black men. Cell phone footage saw 37-year-old Sterling shot and killed by two Baton Rouge, La., police officers after pinning him to the ground early Tuesday. The death has spurred a civil rights investigation by the Justice Department.

Castile, 32, was killed after a police officer opened fire on him during a traffic stop in Minnesota. The aftermath of the death was shown in a Facebook Live video shot by Castile's girlfriend, who was a passenger in the vehicle.
