After posting a letter on her website in response to the deaths of Alton Sterling and Philando Castile, recent tweets showed Beyonce asking the audience at her Glasgow, UK show Thursday (July 7) on the Formation World Tour for a moment of silence for police brutality victims.

The singer also projected dozens of victims’ names on a giant screen onstage, including 37-year-old Alton Sterling and 32-year-old Philando Castile, who were fatally shot by police officers in Baton Rouge, La., and Falcon Heights, Minn., respectively, this week.

“We are sick and tired of the killings of young men and women in our communities,” wrote Bey in her post. “It is up to us to take a stand and demand that they ‘stop killing us.'” She added, “While we pray for the families of Alton Sterling and Philando Castile, we will also pray for an end to this plague of injustice in our communities.” She also inserted links to contact local politicians and voice protests for both victims.
