CIUDAD JUAREZ, Mexico Thirty-five animals at a zoo in the northern Mexico state of Chihuahua have frozen to death during the region's coldest weather in six decades.

Serengeti Zoo owner Alberto Hernandez says 14 parrots, 13 serpents, five iguanas, two crocodiles and a capuchin monkey died. He said Saturday that power failures cut off electrical heating at the zoo in the town of Aldama.

Temperatures have dropped to 9 degrees Fahrenheit (minus 13 Celsius) in the area, the coldest weather in 60 years.

Power outages have affected much of northern Mexico, forcing factories and businesses to close. Dozens of people are in shelters. Schools have been closed in Chihuahua state but are expected to open Tuesday as the weather warms.
