If the plan is finalized, it would allow critical aid to flow to Ukraine as it endures one of Russia’s heaviest assaults of the war.

WASHINGTON — The United States is selling weapons to its NATO allies in Europe so they can provide them to Ukraine as it struggles to fend off a recent escalation in Russia’s drone and missile attacks, President Donald Trump and his chief diplomat said.

The US president said he will send weapons to Nato, which he said would pay and then give the weapons to Ukraine.
