French President François Hollande on Tuesday slammed Donald Trump, saying his attacks on a slain soldier's parents were sickening.

"His excesses make you want to retch, even in the United States, especially when — as was Donald Trump's case — he speaks ill of a soldier, of the memory of a soldier," Hollande told journalists in Paris, AFP reported.

He was referring to Trump's attacks on Khizr and Ghazala Khan, the Muslim parents of a decorated American soldier killed in Iraq.

Khan’s parents took to the stage at the Democratic national convention to talk about their son’s sacrifice and described Trump as “totally unfit for the leadership of this beautiful country.”

Trump responded by insinuating that Khan’s mother, Ghazala, did not address the convention, instead standing silently by her husband Khizr’s side, because of their faith. “If you look at his wife, she was standing there,” Trump said. “She had nothing to say. She probably, maybe she wasn’t allowed to have anything to say. You tell me.”

Hollande criticized Trump's "hurtful and humiliating comments," saying that in November's U.S. election "democracy is also at stake, as we see more and more people tempted by authoritarianism."

"Should the American people choose Trump, there will be consequences because a U.S. election is a global election," he said.

In July, Trump said the terror attacks had changed France.

Speaking about a rise in Islamist terrorism, he told supporters in Florida: “It’s only going to get worse, and it’s going to start getting bad in our country. We’re letting people come in by the tens of thousands.”

“You see what happened to the French priest. A friend of mine, he said he was going to France like three or four months ago. I saw him yesterday. I said how did you like France? He said, I wouldn’t go to France … Because France is no longer France.”

“They won’t like me for saying that, but you see what happened in Nice, you see what happened ... with the priest, who is supposed to be a spectacular man. France is no longer France. And this world better be very careful and they better get very tough and very smart, and they’ll never do it with Hillary Clinton.”
