The US and other NATO member states have already sent Ukraine 17,000 anti-tank missiles and 2,000 Stinger anti-aircraft missiles.
A high-ranking Pentagon official told CNN.
According to the official, even before the invasion of Russia on February 24, military transport aircraft of the USA and other countries arrived in Europe. They were redeploying troops along NATO's eastern flank, as well as delivering weapons to tipping points from where they could be sent to Ukraine.
After the Russian invasion began, 14 countries sent security to Ukraine, a senior U.S. Defense Department official said.
According to the official, the vast majority of the $350 million U.S. security aid package was delivered to Ukraine just one week after the aid was officially approved by the White House.
As a reminder, British Prime Minister Boris Johnson told Ukrainian President Volodymyr Zelensky on Sunday that he would work with international allies to further provide Ukraine with defense weapons.
Ukraine's Defense Ministry on Monday reported significant progress in arms deliveries from abroad, saying it would be a "surprise" to the Russians.
