Dozens of people were arrested outside headquarters of The New York Times on Saturday after a demonstration to demand that the newspaper refer to climate change as an emergency.

A New York City Police Department spokesman told Reuters that 67 people were arrested. Charges against the activists are pending.

The demonstrators, who were reportedly affiliated with the environmental group Extinction Rebellion, attached a sign reading “climate change = mass murder" to the Times' building. The word "change" was crossed out and replaced it with "emergency."

Another sign was affixed to the Port Authority Bus Terminal located across the street from the newspaper's headquarters, Reuters reported. That banner simply read "emergency."

Protestors also blocked the street in front of the office while participating in a "die in," according to the news service.

Police later removed the banners and arrested individuals who had climbed atop an overhang of the Times' building.

Extinction Rebellion describes itself as an environmental group whose mission is to create a "world that is fit for generations to come." The group adds on its website that it is a "non-violent rebellion against the U.S. government for its criminal inaction on the ecological crisis."

"The New York Times can take the lead reporting on the climate emergency," Eve Mosher, a spokesman for the group, told CNN . "They should be treating it like World War II. Where there were headlines every day."

The newspaper stood by its reporting of the climate crisis in a statement to CNN, saying that no national news organization "devotes more time, staff or resources to producing deeply reported coverage to help readers understand climate change."
