Justin Bieber appeared in Mexico City a day after the massacre in Texas.
Justin Bieber was moved during a recent concert. While in Mexico City as part of the "Justice World Tour", the 28-year-old singer cried in front of the audience.
He later posted an excerpt from that moment on his Instagram account, writing: "Tears fill my eyes with hope for humanity."
Justin Bieber gave a concert in Mexico City after the massacre at Robb Elementary School in Uvalde, Texas, where an 18-year-old opened fire and killed 19 children and two members of the teaching staff.
During his concert at the Foro Sol Stadium in Mexico City, Justin Bieber spoke in an emotional tone about unity and acceptance.
"All are equal. In this world, there is a lot of division and a lot of racial injustice, but we can be the ones who make the difference. "We can come together and unite and celebrate with each other, because we are all the same," he said.
"Racism is bad and it is diabolical, but we are together in it and I love you so much," he added.
Justin Bieber wrote in the caption of the video: "Injustice wherever it is is a threat to justice everywhere."
Earlier this month, the pop singer gave a concert in Buffalo, New York a few hours after another horrific massacre, where an 18-year-old gunman cold-bloodedly killed 10 people in a city supermarket.
During his concert, Justin Bieber held a minute's silence in memory of the victims.
"As you know, a tragedy happened in the city, but what we are going to do tonight is honor these people and I would really like to keep a minute of silence. "That would mean a lot to me," he told the audience.
He went on to say that there is "so much division" and "so much racial injustice" in the world.
"We must be the people who will continue to have these conversations with our friends, our families and our loved ones, who will continue to be allies," he said.
