Philippine President Rodrigo Duterte has again lashed out at Barack Obama, this time telling the U.S. president that he can "go to hell."
In a speech Tuesday, the Philippine leader also slammed the European Union, which he said could "choose purgatory, hell is filled up."
The comments were in response to Western criticism of Manila's anti-drug campaign that has killed more than 3,000 people in three months.
Since taking office at the end of June, Duterte has consistently painted the Western criticism as interference from colonial powers.
The comments come as Manila and Washington on Tuesday launched annual military exercises. Duterte has said the war games with the U.S. will be the last in his six-year term.
Duterte has repeatedly threatened to scale back his country's longstanding military cooperation with the U.S., saying he will move closer to Russia and China.
The comments have called into question one of Washington's most crucial military alliances in East Asia. However, so far Duterte has failed to translate any of his threats into action.
No stranger to profanity
Duterte, the former mayor of Davao, has a reputation for hitting out at his critics with profanity-filled tirades.
Last month, hours before he was scheduled to meet the U.S. leader, Duterte called Obama the "son of a whore." The U.S. canceled the meeting.
Duterte was forced to apologize earlier this week after he compared his war on drugs to the Nazi Holocaust of World War II.
Duterte had said: "Hitler massacred three million Jews... there's three million drug addicts. I'd be happy to slaughter them."
On Sunday, he acknowledged that the comments left a "bad taste" in many mouths, and apologized to the world's Jewish community.
But he said he will not apologize to the critics of his tough and often violent crackdown on suspected drug users, producers and sellers.
