The Philippine president has criticized the United Nations for condemning killings of suspected drug criminals in his country.

President Rodrigo Duterte chided the U.N. for being "easy to be swayed into interfering into the affairs of the republic" and "coming on a very stupid proposition."

He was apparently referring to condemnations by U.N. Secretary General Ban Ki-Moon in June and by the U.N. Office on Drugs and Crime earlier this month of his "apparent endorsement of extrajudicial killings."

Critics of his anti-drug campaign said in their last count that about 1,000 people have been killed. Duterte said in his speech Wednesday that some of those were killed by drug criminals.
