Philippines President Duterte Calls Obama 'Son Of A Whore'

Philippines president Rodrigo Duterte has warned Barack Obama not to question him about extrajudicial killings, or "son of a whore I will swear at you".

Despite it being unclear whether the US president would raise the subject when the two men attend the ASEAN summit in Laos this week, Mr Duterte was asked by a reporter how he would explain himself if he did.

More than 2,400 suspected drug traffickers and users have been executed since Mr Duterte launched a war on drugs after taking office at the end of June.  

"I don't give a s*** about anybody observing my behaviour," he said.

"I am a president of a sovereign state and we have long ceased to be a colony.

"I do not have any master except the Filipino people, nobody but nobody.

"You must be respectful. Do not just throw questions. Son of a whore, I will swear at you in that forum," he said.

Referring to his critics, he added: "There are others who have the mental capacity of dogs who lap at the ass of the Americans."   

Mr Duterte also said his country had not received an apology for alleged misdeeds committed during the US colonisation of the Philippines in the last century.
