The superstar, who has publicly supported and highlighted the Black Lives Matter movement, took to her website on Thursday (07Jul16) to weigh in on the deaths of Louisiana man Alton Sterling and Minnesota resident Philando Castile, who both lost their lives in encounters with cops this week (begs04Jul16).

In her lengthy statement, Beyonce echoed the feelings of anger and disbelief from many of her fellow celebrity activists, including John Legend, Katy Perry, Nicki Minaj, and Lena Dunham, who have all expressed outrage over officers' latest use of excessive force with African-Americans.

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

"We don't need sympathy. We need everyone to respect our lives. We're going to stand up as a community and fight against anyone who believes that murder or any violent action by those who are sworn to protect us should consistently go unpunished.

"These robberies of lives make us feel helpless and hopeless but we have to believe that we are fighting for the rights of the next generation, for the next young men and women who believe in good."

However, Beyonce goes on to insist the fight for equal rights is a fight for the whole human race, regardless of creed or colour.

She continues, "This is a human fight. No matter your race, gender or sexual orientation. This is a fight for anyone who feels marginalized, who is struggling for freedom and human rights.

"This is not a plea to all police officers but toward any human being who fails to value life. The war on people of color and all minorities needs to be over. Fear is not an excuse. Hate will not win."

The Halo singer concludes her message by encouraging fans to protest peacefully by lobbying lawmakers to enact sweeping changes to put an end to the unnecessary acts of violence.

"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 writes. "Your voice will be heard."

Beyonce recently faced criticism for appearing to include anti-police imagery in her music video for the song Formation, while including nods to the Black Lives Matter movement and revolutionary 1960s black nationalist organisation the Black Panther Party in her headline-grabbing performance of the track at the Superbowl in February (16).

She also showed her support to the mothers of Trayvon Martin and Mike Brown, who were killed by cops, by including them in the short film which accompanied her latest album, Lemonade. They were featured in the footage holding up photos of their loved ones.

The Black Lives Matter movement was founded by African-American activists in response to George Zimmerman's 2013 acquittal of Trayvon's murder and unprosecuted deaths of young black men in U.S. police custody.
