Russia captures Kostiantynivka: Peskov confirms takeover

Drones also struck on the Russian-controlled side of the Zaporizhzhia region. In an attack on a market in Tokmak, about five people were killed and another 18 injured, according to the local governor. The region was hit by at least 50 attacks during the day, military governor Ivan Fedorov said.

Counterattacks and the drone war

Ukraine responded with drone strikes on Russian energy infrastructure. According to two people familiar with the matter, a drone hit the main refining unit of Norwegian energy company Norsi, which accounts for 53 percent of total capacity. Details on damage or production losses were not initially released.

On the Moscow-annexed Crimean Peninsula, the energy supply deteriorated dramatically. "The enemy is attacking the peninsula's power grid with drones daily. The situation is difficult," said Moscow-installed governor Sergei Aksyonov, according to the Tass agency. "Currently, more than ten districts are entirely or partially without electricity."

Consequences for Crimea

The news about the fall of the city was broadcast on July 3, 2026, on the program Deutschlandfunk. With the capture control of another major city, Russia is expanding its operational space for possible further advances toward Sloviansk and Kramatorsk, the last major Ukrainian defensive positions in the Donbas.

Analysts see the development as a tactical confirmation of Russia's "attrition strategy" with high manpower and material-intensive assaults. Ukraine is likely to now attempt to retake the city in counteroffensives lasting several weeks, which is likely to further worsen the humanitarian situation.

The diplomatic consequences of the reported capture also remain unclear. Western governments, which have so far supported Kyiv with arms deliveries and financial aid, must decide whether and how to respond to the frontline collapse.

At the same time, concern is growing over a humanitarian crisis in the region. Reports of looting, displacement, and forced evacuations from contested suburbs are increasing. Aid organizations are calling for independent access in order to care for the wounded and distribute food rations to the remaining population.

Outlook and possible responses

Overall, the situation remains unclear: Moscow speaks of full control, Kyiv questions the account and announces counterattacks. Independent observers on the ground are not accessible, complicating the verification of Russian claims.

With each frontline shift, a spiral of escalation looms between retaliatory strikes on energy facilities and retaliatory strikes on civilian targets. Russia and Ukraine appear to have entered a race for operational advantages that further undermines the already fragile hope for a ceasefire.
