In an incredibly emotional speech (above) during a vigil held in Los Angeles on Monday, Lady Gaga paid tribute to the victims of Sunday night’s mass shooting in the Pulse nightclub in Orlando, Florida, where 49 people were killed and many others left injured.

Speaking to the crowd gather at LA’s City Hall, Gaga was on the verge of tears as she spoke of the horrific attack. “As we have now witnessed the largest mass shooting in American history, I can’t help but feel that this level of hatred, like all prejudicial crimes, this is an attack on humanity itself. This is an attack on everyone.” She continued: “Tonight, I gather humbly with you as a human being, in peace, in sincerity, in commitment, in solidarity, to take a real moment and mourn the tragic loss of these innocent, beautiful people.”

The “Born This Way” singer – a staunch activist for, and supporter, of LGBT rights – also spoke of the victims themselves, imploring the crowd to keep hopeful. “Let’s all, today, pledge an allegiance of love to them, and to their families, who are suffering so deeply,” she said. “They are sons and daughters, they’re fathers and mothers, they are all our brothers and our sisters.” At the end of her speech, she read out names of some of the victims killed in the attack as the crowd listened in silence.
