Appearing Monday at a vigil in Los Angeles to remember the victims of an attack on an Orlando gay nightclub, Lady Gaga called the massacre an “attack on humanity itself.”

Thousands gathered at City Hall to remember the 49 people killed and dozens injured in Sunday's attack.

“This level of hatred … is an attack on humanity itself,” an emotional Lady Gaga told the crowd.

“This is an attack on everyone. Tonight, I gather humbly with you as a human being in solidarity to take a real moment and mourn the tragic loss of these innocent people. Let’s all today pledge an allegiance of love to them and their families. They are sons and daughters, mothers and fathers.”

“Everyone here, we represent the compassion and the loyalty of millions of people around the world – you are not alone. Orlando, we are united with you and we are here to remember,” she added.

Lady Gaga led off the reading of the names of the 49 victims.
