The singer has become the latest star to speak out after protests broke out in the Maryland city following the funeral of Freddie Gray, 25, who suffered fatal injuries in police custody last week (ends26Apr15).

She has posted a number of candid pictures on her page, including a shot of Time magazine's latest cover showing an image of the riots, and she urged fans to make donations to the National Association for the Advancement of Colored People (NAACP) to fund the clean-up efforts.

Beyonce writes, "People are hurting. Join us in supporting the NAACP to help in the clean-up efforts and to provide housing, food and supplies to those affected by the unrest in Baltimore."
