PARIS — President François Hollande of France has said that the “excesses” of Donald J. Trump made people “want to retch,” adding a scathing international voice to the chorus of those criticizing the Republican presidential nominee.

Speaking on Tuesday to the French Presidential Press Association in Paris, Mr. Hollande noted the worldwide importance of the American campaign, calling it a “global election,” and said a victory for Mr. Trump could herald a shift to conservative candidates in other countries.

Mr. Hollande, whose comments were later reported by Agence France-Presse and Reuters, expressed particular dismay at the attacks on “a soldier, the memory of a soldier,” referring to Mr. Trump’s continued criticism of the parents of Capt. Humayun Khan, a Muslim and an American soldier who was killed in 2004 in Iraq.

The comments from Mr. Trump have prompted widespread condemnation in the United States and have led several prominent Republicans to distance themselves from the party’s nominee.
