"We will not tolerate the use of chemical weapons in Europe, in Russia or in Syria," Emmanuel Macron told the U.N. General Assembly.
"This clarification must be swift and flawless because we will enforce our red lines," Macron said. The Kremlin has denied any involvement.
Macron did not elaborate on what would be done if Russia did not provide satisfactory explanations.
INTERPRETER: We will not tolerate chemical weapons being used in Europe, Russia, or Syria. On behalf of collective security, I restate here to Russia that light needs to be shed on the assassination attempt against a political opponent using a neurotoxic agent, Novichok. This clarification needs to take place quickly and without fault because we will enforce our red lines. And on this topic, France has always been prepared to enforce the effectiveness of red lines or at least since I've been president of the republic.
