The streets of Mexico City were flooded with hundreds of zombies who roamed around for fun and also to extend help to quake victims. The country is still lamenting the death of over 500 people killed in September's earthquakes. Wearing frightening costumes, make-up and masks, the horde of self-proclaimed "undead" gathered at the city’s Monument to the Revolution and later marched on the city's iconic Zocalo. People participating in the city's tenth annual Zombie Walk helped collect canned and non-perishable goods for quake victims.
