Ukraine launched strikes against oil infrastructure targets inside Russia and in Crimea, officials confirmed Sunday, marking another escalation in Kyiv's campaign to degrade Russian energy assets and logistics networks that support the war effort. The attacks targeted fuel storage and processing facilities, though specific damage assessments were still being compiled.

The strikes came as European heads of government convened at Downing Street in London, where British Prime Minister Keir Starmer hosted Ukrainian President Volodymyr Zelensky alongside French President Emmanuel Macron and German Chancellor Friedrich Merz. The summit focused on the urgent need to supply Ukraine with stronger air defense systems capable of intercepting Russian ballistic missiles, which have caused significant civilian casualties in recent months.

European leaders stressed that air defense gaps remain one of the most critical vulnerabilities in Ukraine's defensive posture, and discussed accelerating deliveries of surface-to-air missile systems. No specific new commitments were immediately announced following the London talks, though participants described the discussions as constructive and ongoing.

In Washington, Representative Michael McCaul, a senior Republican voice on foreign affairs, said the United States needed to take a tougher stance toward Russia and expressed support for supplying Ukraine with additional military capabilities. His comments reflected a continued debate within U.S. policy circles over the scope and pace of American assistance to Kyiv.

The combination of Ukrainian offensive strikes, high-level European diplomacy, and renewed calls for stronger U.S. engagement underscores the broad, multi-front nature of efforts to sustain Ukraine's war effort more than four years after Russia's full-scale invasion began.
