North Korean leader says purge was a cleansing of 'filth'

SEOUL (Reuters) - North Korean leader Kim Jong Un made his first reference to the execution of his powerful uncle in a New Year's address, saying the reclusive state's ruling party had become stronger after it was purged of "factional filth."

And he called for better relations with South Korea, warning that another war on the Korean peninsula would cause a massive nuclear disaster that would hit the United States.
