"As for thwarting the Russians' counteroffensive actions — there are not enough appropriate weapons [in Ukraine]," the Ukrainian president said during an appearance on a national news broadcast.
Ukraine's armed forces are attempting to compensate for the shortage of artillery shells with drones, which "help but cannot be an alternative," he added.
Western countries have ramped up military and financial aid to Ukraine since the start of Russia's military operation in February 2022. The Kremlin has consistently warned against continued arms deliveries to Kiev, saying they would lead to further escalation of the conflict.
Unprecedented military support for Ukraine has led to a depletion of US arms stockpiles while European countries have mulled expanding the continent's weapons production capabilities. Meanwhile Russia has stunned observers with the quality of its weapons output, leading the way in new technologies such as hypersonic missiles.
