Rodrigo Duterte calls Barack Obama a 'son of a whore' – video

Barack Obama has cancelled a meeting with the president of the Philippines after Rodrigo Duterte appeared to call him a “son of a whore’. The move followed a warning from Duterte to the US president to stay away from the subject of extrajudicial killings in his country’s brutal drug war when they were due to meet on Tuesday at a regional summit in Laos.
