An internal U.N. analysis has found Russia responsible for a 2022 explosion at Olenivka prison, which killed over 50 Ukrainian prisoners of war (POWs), Ombudsman Dmytro Lubinets said on June 30.

"(A)n internal analysis of the U.N. showed that it was the Russian Federation that planned and carried out the attack," he said in a post to social media.

Lubinets referred to a report by the Center for Human Rights in Armed Conflict, whose website features only the investigation into the Olenivka explosion.

The investigation, published on June 26, reads that an "internal U.N. analysis concluded that it was the Russian Federation who planned and executed the attack," though the U.N. did not publicly acknowledge Russia's responsibility.

Russia has denied being responsible for the attack but prevented efforts by the international community to independently investigate the attack and contaminated evidence at the site, according to a report published by the U.N.

Kyiv has said that days before the July 2022 attack, Russia deliberately put Ukrainian members of the Azov Regiment, who were awaiting a prisoner exchange, in a separate part of the Olenivka prison building that was later destroyed in the explosion.

"The report identifies the weapons and ammunition that the Russian Armed Forces used to kill Ukrainian prisoners of war, and also examines in detail the planning, organization, and execution of the murder," Lubinets said.

The ombudsman noted that the U.N. fact-finding mission on Olenivka was disbanded due to a lack of security guarantees, adding that the mission has previously refused to review evidence provided by Ukraine.

Russia has repeatedly violated international conventions protecting the rights of POWs as it continues to carry out its war against Ukraine.

A Russian military court has convicted 184 Ukrainian POWs captured in Kursk Oblast of acts of terrorism, Mediazona reported on June 25.

The POWs captured in Kursk were charged with carrying out a grave terrorist act by a group of individuals, as outlined by the Russian Criminal Code.

Junior Lieutenant Yevhen Hoch was convicted of allegedly carrying out an act of terrorism by taking part in Ukraine's Kursk Oblast incursion.

Ukrainian forces reportedly struck a Russian logistics hub and an oil depot in Russian-occupied Luhansk and a military base in occupied Donetsk on June 30 and July 1, with fires breaking out in the two cities.

"Russian logistics in temporarily occupied Luhansk are burning," head of Ukraine's Center for Countering Disinformation Andrii Kovalenko said.

The drone attack was reported by the local media, publishing what appear to be videos of the burning logistics hub and the sound of drones.

Leonid Pasechnik, head of the Russian occupation authorities in Luhansk Oblast, reported that air defenses shot down 35 of the 40 drones over Luhansk Oblast. Drone wreckage fell on the premises of an oil depot, and a woman was injured, Pasechnik claimed.

Overnight Ukrainian attacks were also reported in occupied Donetsk, with Telegram news channels sharing apparent footage of damaged buildings and fires in the city.

Denis Pushilin, the head of the Russian occupation authorities in Donetsk Oblast, claimed that one person was killed and three were injured in the attack. Ukrainian news channel Supernova+ reported that the attack targeted the headquarters of Russia’s 8th Combined Arms Army.

The Ukrainian military has not commented on the claims, which could not be independently verified.

Ukraine's military regularly strikes military targets in Russian-occupied territories and deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Ukraine's military intelligence (HUR) destroyed three Russian air defense systems using drones in the occupied Zaporizhzhia Oblast on June 14.

"Strike drone masters of the Department of Active Operations of the HUR of the Ukrainian defense ministry discovered and destroyed expensive air defense systems of the Russian invaders in the temporarily occupied territory of the Zaporizhzhia region," HUR reported in a post to Telegram.

A Russian Buk-M3, a Pantsyr S1, and a 9S19 Imbir radar from the S-300V air defense system were destroyed in the Ukrainian drone attack.
