Philippine President Rodrigo Duterte has threatened to throw corrupt officials out of a helicopter mid-flight and kill drug lords under his administration.

Duterte made the statement at a speech while visiting typhoon victims in the Camarines Sur province.

He said that he has thrown criminals out of a helicopter before while he was mayor of Davao.

He also commented on a drug raid in downtown manila on Friday that he would personally kill the six suspects who were arrested for having more than 560kg of local methamphetamines worth $67 million.

More than 6,000 people have been killed in the crackdown since Duterte took office in July, roughly a third in police operations.
