RAMSTEIN AIR BASE, Germany (AP) — Defense Secretary Lloyd Austin urged allied defense leaders Tuesday to “dig deep" and provide more air defense systems for Ukraine to help it block increasing barrages of Russian missiles, even as debate grows in Congress over aid to Kyiv.

But while the allies said they will discuss how they can best help in the coming winter months, they appeared no closer to commitments on the longer-range missiles that Kyiv's leaders insist they need as they struggle to retake land gained by Russia earlier in the conflict.
