MANILA -- Australia says rape and murder should never be joked about after the leading Philippine presidential candidate Rodrigo Duterte said last week that he “should have been the first” to assault an Australian missionary who was gang raped and killed by prisoners in 1989.

YouTube user Beatboxer ng Pinas uploaded a video of Duterte, who attended a campaign rally in Quezon City last Tuesday, April 12, talking about the killings of 36-year-old Australian Jacqueline Hamill and four other missionaries in Davao City.

Hamill and other women hostages were also raped.

Duterte's video went viral and has gathered a lot of reactions.

In the video, Duterte said he was angered because Hamill was so beautiful and the prisoners took turns raping her when “the mayor should have been first.”

Ambassador Amanda Gorely tweeted late Sunday that “rape and murder should never be joked about or trivialized.”

Duterte said on Sunday that he saw no need to apologize for saying he should have had the woman first.

“If it brings me down, let it bring me down. If it brings me up to the presidency, then well and good. I will serve you but I will not as a matter of honor, apologize for it,” he told some journalists. (AP/Sunnex)
