Canada first nation to pull out of Kyoto protocol

OTTAWA (Reuters) - Canada on Monday became the first country to announce it would withdraw from the Kyoto protocol on climate change, dealing a symbolic blow to the already troubled global treaty.

Environment Minister Peter Kent broke the news on his return from talks in Durban, where countries agreed to extend Kyoto for five years and hammer out a new deal forcing all big polluters for the first time to limit greenhouse gas emissions.
