The conflict between Ukraine and Russia has entered a new phase of escalation, marked by a significant increase in drone warfare targeting critical infrastructure. On June 18, 2026, Ukrainian President Volodymyr Zelensky confirmed that drone strikes had successfully targeted a major oil refinery in Moscow, framing the action as a direct response to Russian attacks on Ukrainian religious and cultural sites. Consequently, Russian authorities grounded all flights at major Moscow airports, including Sheremetyevo and Vnukovo, citing safety priorities as the airspace remained restricted.
How is the conflict over energy infrastructure evolving?
The recent targeting of oil refineries represents a shift toward economic warfare, aimed at degrading the logistical support for Russia’s military operations. According to President Zelensky, these strikes are a “just response” to Russian bombardments of Ukrainian cities. Data from the Russian news agency Tass indicates that the scale of these operations is intensifying; the June 18 raid involved a massive wave of drones, described as one of the largest since the beginning of the conflict, following a similar pattern observed throughout May and June 2026.

The intensity of drone warfare has spiked significantly. Tass reports that 555 drones were intercepted over Russian territory on June 18, 2026, marking the second-highest daily total recorded since the start of the current escalation phase.
Why are European diplomatic channels under scrutiny?
The role of international mediators has become a flashpoint for debate within the European Union. Following reports that the office of European Council President Antonio Costa initiated quiet communication with Moscow, diplomatic friction has emerged among the 27 member states. While some high-level EU diplomats maintain that the President of the European Council is the appropriate official to represent the bloc in potential peace talks, other member states expressed surprise at the lack of prior coordination. This internal tension contrasts with the unified stance shown during the June 18 EU summit, where all 27 nations approved a long-term strategy for sanctioning Russia.

What is the current state of the diplomatic push for peace?
Diplomatic efforts are currently fragmented, with multiple actors vying for a seat at the table. While the European Union debates its own internal representation—with figures like Roberta Metsola emphasizing the need to respect the principle of “nothing about Ukraine without Ukraine”—other external powers remain active. Russian presidential advisor Yuri Ushakov recently stated that the current military escalation on both sides is actively hindering the potential for a direct summit between Vladimir Putin and Volodymyr Zelensky. Meanwhile, the Kremlin continues to dismiss Western-backed peace initiatives as “false offers,” maintaining that their core demands regarding the Donetsk region remain unmet.
