WASHINGTON/BELGRADE (Reuters) - Serbia has agreed to supply arms to Kyiv or has sent them already, according to a classified Pentagon document, despite the country's professed neutrality in the Ukraine war and refusal to sanction Russia over its 2022 invasion.
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.
