U.S. Republican Senator Lindsey Graham took aim at French President Emmanuel Macron for his "cavalier" remarks on European Deash/ISIS fighters.

Axar.az reports citing foreign media.

"Very disturbed by the cavalier remarks made by President Macron about how the number of European ISIS fighters in Syria is a small problem in the grand scheme of things," Graham said on Twitter.

Graham's rebuke came a day after U.S. President Donald Trump clashed with Macron over the repatriation of Daesh/ISIS terror group fighters currently held in northeastern Syria.

Speaking to reporters during a NATO leaders summit in London, Trump criticized Europe's reluctance to take back its nationals, saying foreign fighters detained in Syria "are mostly from Europe."

He then turned to Macron and asked if the French president would "like some nice ISIS fighters?"

"I can give them to you. You can take every one you want," Trump said before Macron quickly rebuffed the U.S. president, saying "let's be serious."

"A very large number of fighters you have on the ground are fighters coming from Syria, Iraq and the region," Macron said. "It's true that you have foreign fighters coming from Europe, but this is a tiny minority of the overall problem that you have in the region."

Graham said there are hundreds of European Daesh fighters imprisoned in Syria and said the Paris and Nice attacks in France were carried out by "a handful of ISIS fighters."
