Eleven children died of exposure as a rare cold front sent temperatures below freezing in northern Mexico on Friday.
The fatalities brought to at least 50 the number of deaths from unusually cold temperatures in the past four weeks. Temperatures in Mexico City dipped to 48 degrees overnight, but readings of nearfreezing were reported at mountain elevations above 13,000 feet.
Mexico City residents awoke to a view of white-topped mountain peaks and volcanoes, normally obscured by smog. Many flocked to the mountains of nearby Ajusco peak to play in the snow.
