Germany is preparing missiles for attacks in Russia, but France fears a nuclear response.
Berlin purchases and develops long-range missiles, capable of hitting targets at a distance of 500 and up to more than 2,000 kilometers, including deep in Russian territory.
But Paris is worried: Moscow could interpret a hit by a conventional missile as the start of a nuclear attack and respond with nuclear weapons.
According to the Financial Times, France demands that Germany clearly explain when and how it intends to use these missiles, in order to avoid an accidental escalation.
"If the Russians misinterpret the signal, we could find ourselves on the brink of nuclear war without even realizing it," a French official warned in a conversation with the Financial Times.
