Serbia, the only country in Europe that has refused to sanction Russia for its military operation in Ukraine, agreed to supply arms to Kyiv or has sent them already, according to a classified Pentagon document, Reuters reports.
The document, a summary of European governments' responses to Ukraine's requests for military training and "lethal aid" or weapons, was among dozens of classified documents posted online in recent weeks in what could be the most serious leak of U.S. secrets in years.
Serbia's Defense Minister Milos Vucevic dismissed the intel as "untrue" in a statement on Wednesday.
"Serbia did not, nor will it be selling weapons to the Ukrainian nor the Russian side, nor to countries surrounding that conflict," Vucevic said.
Entitled "Europe|Response to Ongoing Russia-Ukraine Conflict," the Pentagon document in chart form lists the "assessed positions" of 38 European governments in response to Ukraine's requests for military assistance.
The chart showed that Serbia declined to provide training to Ukrainian forces, but had committed to sending lethal aid or had supplied it already. It also said Serbia had the political will and military ability to provide weapons to Ukraine in the future.
The document is marked Secret and NOFORN, prohibiting its distribution to foreign intelligence services and militaries. It is dated March 2, and embossed with the seal of the office of the Joint Chiefs of Staff.
In his statement, Defense Minister Vucevic said there was a possibility that Serbia-made weaponry and ordnance could "magically appear" in the conflict, but "that has absolutely nothing to do with Serbia."
"This is the question for countries that do not respect international norms, contractual clauses and business practices," he said, dismissing the intelligence document.
"Someone clearly wants to drag Serbia into that conflict, but we are diligently maintaining our policies."
President Aleksandar Vucic's office and the Ukrainian embassy did not immediately respond to a Reuters request for comment.
The Pentagon also did not immediately respond to Reuters questions about the document's reference to Serbia and has previously declined to comment on any of the leaked documents.
