The US military has decided to send F-16 fighter planes to Ukraine from Denmark and the Netherlands as soon as the training of Ukrainian pilots is completed.

Moscow has warned that Russia will see as a 'nuclear threat' the US-made F-16 warplanes in Ukraine.

The Russian foreign minister has warned that US-built F-16 fighter jets can carry nuclear weapons if they are sent to Ukraine.

The Polish prime minister says his country will help Ukraine train its pilots to fly US-made F-16 fighter jets.

Foreign Minister Lavrov said he had “no doubt that our armed forces have the ability to react to this.”

Russia has warned that supplying more destructive and advanced weapons by the US and its allies to Ukraine increases the probability of a "nuclear apocalypse.”

US may suffer logistical challenge by supplying Ukraine with advanced fighter jets including F-16s following months of Ukrainian government requests, since there a possibility that the fighter or its technologies could fall into Russian hands or it could face significant losses in combat, according to an American magazine.

Washington has changed its policies on fighter jets after Volodymyr Zelensky’s repeated requests to send F-16 fighters.

Germany says it does not have the military capabilities to be part of a coalition to supply Ukraine with warplanes.
