France is summoning U.S. Ambassador Charles Kushner after he criticized French President Emmanuel Macron's response to rising antisemitism in the country.

France summoned the American ambassador Charles Kushner after he wrote a letter to French President Emmanuel Macron alleging France had failed to do enough to stem antisemitic violence, a French foreign ministry spokesperson said on Sunday.

A diplomatic row between the United States and France escalated on Monday when Washington decided to stand firmly behind its ambassador's criticism of the French response to a rising tide of antisemitism.
