Iran's supreme leader Ayatollah Ali Khamenei said Tuesday that Donald Trump's presidency shows the United States is in "decline", as the Islamic republic marked 30 years since the death of its founder.
"The fate of more than 300 million humans is in the hands of a person with such characteristics, this is a sign of America's political decline," Khamenei said in a speech broadcast live on state television.
"In America itself there is so much discussion on his mental and moral stability," he said, attending a ceremony at the mausoleum of Ayatollah Ruhollah Khomeini.
"When such a person is the president of a country, this shows the political and moral decline of that country."
