Earlier this month, a senior Ukrainian official said Kiev had agreed on the provision of weapons and military advisers from several members of the U.S.-led alliance. Four of the five countries named, including the United States, denied this.
"We reached agreements in closed talks, without media, about ... those weapons that we currently need," said Heletey, who said Ukraine needed weapons "that could stop Putin".
"I have no right to disclose any specific country we reached that agreement with. But the fact is that those weapons are already on the way to us - that's absolutely true, I can officially tell you," he said.
