Ukrainian strikes in Russia's rear
Ukraine continues to demonstrate capability for long-range strikes on strategic Russian targets. On the night of June 11-12, Ukrainian forces, including units of the Unmanned Systems Forces, attacked the „Rezonit“ plant in the „Zubovo“ technopark, Moscow Region.
According to the General Staff and the Center for Countering Disinformation, the plant produces navigation systems, printed circuit boards, and microelectronics for Russian naval weapons and missiles, including „Kalibur“, Kh-101, „Iskander“, „Lancet“ and “Cube“.
Data from NASA FIRMS for June 12 confirm the presence of thermal anomalies in Zubovo, coinciding with the time and location of the strike.
Exchange of prisoners of war
On June 12, Ukraine and Russia carried out a new exchange of seriously wounded prisoners of war, within the framework of the agreements from the negotiations in Istanbul on June 2. President Volodymyr Zelensky and the Russian Ministry of Defense confirmed the operation.
The head of Ukrainian military intelligence, Lieutenant General Kirill Budanov, specified that among the returned ones there are defenders of Mariupol who spent over three years in captivity. A new round of exchanges is expected in the near future.
Meanwhile, Russia has accused Ukraine of not respecting the agreed terms, including refusing to repatriate the bodies of killed soldiers - allegations that Kiev describes as a disinformation campaign aimed at covering up Russian abuses of prisoners of war.
Support from Southeast Europe
On June 11, the fourth Ukraine-Southeast Europe summit was held in Odessa, hosted by Volodymyr Zelensky. It was attended by leaders from Moldova, Montenegro, Romania, Bulgaria, Croatia, Greece, Albania, North Macedonia and Slovenia.
The participants signed a declaration demanding:
-
Immediate cessation of Russian aggression,
-
Full withdrawal of Russian forces from Ukraine,
-
Accelerated membership of Ukraine in NATO and the EU.
Serbian President Aleksandar Vučić attended the meeting, as this was his first official visit to Ukraine, but did not sign the declaration. He expressed Serbia's readiness to invest in the reconstruction of one or two Ukrainian regions and reaffirmed support for Ukraine's territorial integrity.
Russian officials reacted sharply to Vučić's involvement, claiming that he acted under external pressure.
Increased military aid from Germany
On June 12, President Zelensky announced that Germany had signed a three-year agreement for the supply of IRIS-T air defense systems. Defense Minister Boris Pistorius pledged an additional 1.9 billion euros in 2025, including funds for long-range strike weapons.
This brings the total amount of German support for Ukraine to nine billion euros, subject to approval by the Bundestag.
