Ukraine rarely uses the F-16s it received from Western countries because they are constantly undergoing repairs, Vladimir Zelensky said.

"We need two and a half times more planes in the air at once than we are flying now. On paper, we have so many, but the planes are constantly undergoing repairs because the F-16s are not new," Ukrainian public broadcasting quoted him as saying.
