President Vladimir Putin made a rare admission over this past weekend, belatedly acknowledged Sunday that Russia is facing a "certain shortage" of fuel following weeks of ramped-up drone warfare coming out of Ukraine, which has chiefly targeted oil refineries and domestic supply facilities, including in the Moscow region.

"As for strikes against critical infrastructure in general, and energy infrastructure in particular, of course, these attacks on our infrastructure facilities create problems," Putin said in the new interview published by the Kremlin. "That's obvious."

"Right now we're observing a certain shortage, but it's not critical," he added. He also made wide-ranging public remarks at a major summit of the ruling 'United Russia' party.

Ukraine's Zelensky has made no secret of his plans to make life inside Russia as painful as possible, in order to put pressure on the Kremlin to end the war. By close of last week, the rare national fuel crisis inside Russia was outlined as follows:

Further, a state of emergency for all citizens was also declared in Crimea last week - with fuel only being provided to military and state entities at this point.

Putin further acknowledged in his comments that small, slow-moving drones have proven a problem for Russia's anti-air defense systems, which were conventionally designed to intercept large fast projectiles like missiles or warplanes.

This has been big on Russians' minds, as this month they beheld unprecedented scenes of massive smoke plumes overtaking Moscow's skyline, as a key refinery there burned. Still , the Russian leader sought to project strength, stating:

"Yes, we see the problems, we are aware of them and are responding to them, but we will certainly ensure the security of both the country and our citizens, as well as the inviolability of Russia's borders," Putin said at an earlier speech at the congress of the ruling United Russia party

"We will undoubtedly overcome all the challenges facing us today, including terrorist attacks on our territory and infrastructure facilities," he added.

In the context of the separate Kremlin interview, Putin continued to express hope of positive talks with the US, amid efforts to both improve bilateral relations and negotiate a final political solution to end the Ukraine conflict.

Addresses Ukraine's 'information campaign'...

"We are ready to continue negotiations... and discuss all the details," Putin said, saying that he expects White House special envoy Steve Witkoff and Trump's son-in-law Jared Kushner to visit Moscow after the "active phase" of the war in the Middle East passes.

Russian officials have repeatedly commented on Washington being busy and absorbed with the Iran conflict and Strait of Hormuz crisis.

That Putin is somewhat downplaying the fuel crisis, emphasizing that it's "not critical" - signals that Russia is not yet feeling enough pressure to compromise or capitulate on anything, as Zelensky is hoping.
