COLOMBIAN President Gustavo Petro signed a Bill on Monday that bans bullfights in the South American country, further reducing the short list of nations around the world where the centuries-old tradition is still legal.

Petro signed it in front of hundreds of animal rights activists during a ceremony held in Bogota’s bullring, after a supporter in a bull costume handed him a copy of the legislation.

“We cannot tell the world that killing living and sentient beings for entertainment is culture,” Petro said in a speech after signing the Bill. “That kind of culture of killing an animal for entertainment would also lead us to killing human beings for entertainment, because we are also animals.”
