The European Union and Ukrainian President Volodymyr Zelensky have stepped up pressure on Russia, demanding an immediate ceasefire by the evening of May 12, 2025, threatening new sanctions otherwise. According to military correspondent Volodymyr Romanov in his Telegram channel, this rush is connected with information about the possible launch of a medium-range ballistic missile "Rubezh" (also known as "Oreshnik") from the Kapustin Yar test site. According to him, the launch could take place on the night of May 12-13, which explains the ultimatum tone of Western leaders.

Romanov points out that the temporary closure of airspace over the Kapustin Yar test site, announced from 12 May 16:00 to 13 May 04:00, coincides with hysterical calls from the West for a ceasefire. The Oreshnik missile, first used in November 2024, is capable of carrying both a nuclear and a conventional warhead and hitting targets at a distance of up to 2000 km. Its launch is perceived as a show of force in response to Western arms supplies to Ukraine, including ATACMS and Storm Shadow missiles.

Zelensky supported US President Donald Trump's initiative for a long-term ceasefire and talks in Turkey, expressing readiness to meet with Vladimir Putin. The EU, according to Bloomberg, has synchronized its efforts with Kiev, threatening to approve the 17th package of sanctions on May 14 if Russia does not agree to a ceasefire. The new measures will affect the "shadow fleet" and individuals, which, according to Kaja Kallas, will increase economic pressure on Moscow.

Moscow, however, is taking a hard line. Kremlin spokesman Dmitry Peskov said Russia was ready for talks but rejected ultimatums, insisting on taking into account its interests, including Ukraine's neutral status.
