Russian defence ministry says its forces captured Kostiantynivka in eastern Ukraine

Russian Military Advances and Strategic Developments in Donetsk Region

July 3 (Reuters) - Russia's military told Russian President Vladimir Putin on Friday that its forces had taken control of Kostiantynivka in eastern Ukraine, a key locality whose capture Moscow has long sought in its advance through the Donetsk region.

Putin's Response and Strategic Assessment

Putin, shown in videos visiting a command post and receiving a report from top commanders, praised the city's capture as an important strategic achievement.

He also said Russian forces had to increase the scale of security zones in response to intensified Ukrainian long-range strikes, mainly against Russia's oil industry.

Ukrainian Reaction

Ukraine made no comment on Russia's claim to have seized Kostiantynivka.

Military Reports and Ongoing Operations

General Valery Gerasimov, chief of Russia's General Staff, announced the city's capture in a report on the conduct of the war, now in its fifth year.

Gerasimov said the southern group of forces was carrying out offensive operations to "liberate" all of the Donetsk region, part of the broader Donbas region over which Russia has vowed to secure control as a key aim of its war effort.

Strategic Importance of Kostiantynivka

"The troops of the group have liberated the city of Kostiantynivka, one of the main defensive hubs of the enemy within the Sloviansk-Kramatorsk-Kostiantynivka fortified area", Gerasimov said.

Russia's military has for some time reported that its troops were in control of parts of Kostiantynivka, one of several cities seen as a network of key fortifications in Ukraine's defence of the region.

Putin described the city as having an important strategic significance.

Economic and Industrial Significance

"We all know that this city is a key transport and large industrial centre of Donbas," Putin said.

Visual Evidence and Further Military Movements

Russian Pictures Show Soldiers in City

The Defence Ministry posted images on Telegram that it said were scenes from Kostiantynivka, including pictures of Russian soldiers holding national flags by shattered buildings.

Advances Toward Lyman and Security Efforts

Gerasimov also told Putin that Russian forces were closing in on Lyman, a town about 70 km (45 miles) to the north which he said was "of key logistical and strategic importance for further advances in this direction".

The head of Russia's northern troops, Yevgeny Nikiforov, said his forces had "not yet fully managed to resolve the task" of preventing Ukrainian drone strikes that have hit oil installations and caused fuel shortages in Russia.

Putin responded by saying: "The more attacks the enemy tries to carry out on our civilian facilities ... the larger a security zone we’ll have to establish in the neighbouring territory."

Nikiforov told Putin that Russian troops were making progress in securing border areas in the Kharkiv and Sumy regions, where Moscow has called for expanded buffer zones.

Ukrainian and International Perspectives

Ukrainian Statements and Diplomatic Efforts

Ukrainian President Volodymyr Zelenskiy and other officials have said Russia's advances in eastern Ukraine have slowed considerably since the beginning of the year and Kyiv's forces have even recaptured some territory.

Putin, in his remarks, dismissed Kyiv's statements as an "information campaign in which it puts on display supposed successes". Zelenskiy sent an open letter to Putin last month seeking a direct meeting but the Kremlin leader rejected the proposal.

Peace Talks and International Mediation

U.S.-brokered attempts to move towards a peace deal have been put on hold during the conflict in Iran, but both Moscow and Kyiv say they are anticipating a visit soon by the two top negotiators, Steve Witkoff and Jared Kushner.

Key Takeaways

  • Kostiantynivka is a key defensive hub in Ukraine’s Donetsk ‘fortress belt’—its capture would jeopardize logistics and open access toward Sloviansk‑Kramatorsk (lemonde.fr).
  • Russian forces have been infiltrating the city via attrition tactics over weeks, gradually weakening Ukrainian defenses (lemonde.fr).
  • Despite the announcement, analysts caution that the broader defense line remains intact and further Russian advances remain costly and slow (lemonde.fr).
