France summoned the U.S. ambassador after he publicly alleged that France was failing to rein in antisemitism.

France will summon U.S. Ambassador Charles Kushner to its foreign ministry on Monday after the American diplomat levied sharp allegations against his host country over its “lack of sufficient action” in response to the rise of antisemitism.

France strongly rejected the “unacceptable” allegations in Kushner’s letter, which the ministry said “fall short of the quality of the transatlantic relationship” between the US and France.
