General Staff: Russia has lost 87,310 troops in Ukraine since Feb. 24

The new footage was published just hours after another night of Ukraine successfully attacking military targets on the peninsula.

Some groups of Russian infantry troops have entered the embattled city, and the situation is difficult, but Kostiantynivka remains under the control of the Ukrainian Armed Forces, Head of Ukraine's General Staff Major Andriy Kovalev stressed.

Ukraine's military reportedly carried out an attack on St. Petersburg in the early hours of July 4, striking an oil terminal in the city, Russian Telegram media channels reported.

"The decision will make it possible to hold Russia's senior political and military leadership to account specifically for the crime of aggression, not merely for its consequences," Zelensky said.

The number includes 1,190 casualties that Russian forces suffered over the past day.

Ukraine's military continued its barrage of attacks on targets in Russian-occupied Crimea overnight on July 4, reportedly striking key infrastructure on the peninsula, Russian Telegram media channels reported.

"In Belgorod, infrastructure objects were damaged, as a result of which disruptions in the supply of electricity and water were recorded," acting Governor Alexander Shuvaev reported.

"I note that massive, coordinated strikes against the infrastructure of Ukraine's military-industrial complex and the facilities supporting its operation must continue," Russian President Vladimir Putin said.

Four people have died, including a 5-year-old girl and her mother, authorities in Sumy reported. Another 27 people were injured, with many in serious condition.

The Lukoil-Nizhegorodorgsintez plant is the fourth-largest oil refinery in Russia, second-largest producer of gasoline, and Lukoil's largest refinery.

"Our job as diplomats is to maintain dialogue and utilize every tool in the diplomatic arsenal to solve problems," Foreign Minister Andrii Sybiha said after a meeting with his Polish counterpart. "It is time to set emotions aside."
