About 1,000 animal rights activists staged a protest over the weekend in Mexico City to demand an end to bullfighting, a deep-rooted tradition in Mexico.

The majority of the people who took part in Sunday’s protest showed up at a plaza on the Paseo de la Reforma partially clothed and with simulated blood smeared on their bodies.

The animal rights activists spent about an hour lying on the ground completely silent to simulate the slaughter of bulls, while other protesters chanted slogans against bullfighting.
