'God told me to stop swearing' says Philippine leader Duterte

The Philippine president, who once called the pope a "son of a bitch" and told Barack Obama to "go to hell", says he has promised to God he will not use expletives again.

President Rodrigo Duterte's profanities have become his trademark, especially when threatening to kill drug dealers as part of his war on illegal drugs that has left thousands dead since he took office at the end of June.
