US threatens to block arms for Ukraine over refinery attacks, FT reports - Reuters

The United States has warned that it may suspend the procurement mechanism that supplies weapons to Ukraine if Kyiv continues its deep strikes on Russian energy facilities. The threat is aimed at halting attacks that have targeted Russian oil refineries in recent weeks.

Ukraine’s military has intensified operations against Russian energy infrastructure, striking several refineries in an effort to disrupt fuel supplies. These actions have been described as part of a broader campaign to weaken Russia’s war‑fighting capacity.

In response, U.S. officials have indicated that the flow of arms to Ukraine could be blocked, effectively pausing the delivery of new weapons through the existing procurement system. The move is intended to pressure the Ukrainian government to cease its attacks on the refineries.

The United States’ stance reflects concerns about the escalation of the conflict and the potential for further destabilising effects on regional energy markets. By linking arms deliveries to the conduct of Ukrainian forces, Washington is signalling a willingness to use military assistance as leverage in diplomatic negotiations.

European officials have confirmed the existence of the U.S. warning, noting that the decision underscores the growing tension between supporting Ukraine’s defence needs and curbing actions that target Russian civilian‑related infrastructure. No formal change to the arms supply process has been announced at this stage.
