NATO Secretary-General Jens Stoltenberg, on an unannounced visit to Kyiv, said on Thursday that Ukrainian forces were "gradually gaining ground" in their counteroffensive against Russian forces.
Speaking at a joint press conference with Ukrainian President Volodymyr Zelenskiy, Stoltenberg also said Russian troops were fighting for Moscow's "imperial delusions".
Stoltenberg announced that NATO now had over-arching framework contracts in place with arms companies worth 2.4 billion euros ($2.53 billion) for key ammunition, including 1 billion euros in firm orders.
He said such contracts would allow NATO members to replenish their depleted stockpiles while also continuing to provide Ukraine with ammunition, a key factor in the war.
Stoltenberg also condemned Russian strikes near Ukraine's border with NATO member Romania. He said there was no evidence such strikes were a deliberate attack on Romania but branded them "reckless" and "destabilizing".
