Ukraine is struggling with troop shortages as it tries to repel an advancing Russian offensive on Kharkiv, its top general has admitted.

“All of our forces are either here or in Chasiv Yar,” Gen. Kyrylo Budanov, the head of Ukraine’s military intelligence agency told the New York Times, referring to a Ukrainian stronghold about 120 miles farther south that Russian troops have assaulted in recent weeks. “I’ve used everything we have. Unfortunately, we don’t have anyone else in the reserves.”

The general said that Ukraine was outnumbered as well as outgunned, with the latest US military aid package signed three weeks ago barely beginning to arrive yet.

The coming days would be important, he is reported as saying, with Kyiv believing it can shore up its defensive lines. He believes though that Russia may launch a new attack further north of Kharkiv, in the Sumy region.

Ukrainian troops have been battling the new Russian offensive since Friday, with Moscow claiming that it has already captured nine villages.
