Russian Defence Ministry said on July 3 that its forces had captured Kostiantynivka, a strategic city in eastern Ukraine's Donetsk region, after weeks of intense fighting [1, 2, 3, 4]. Russian General Valery Gerasimov reported the capture directly to President Vladimir Putin during a military briefing [1, 2, 3, 4]. Putin called the operation a "first and very important step" toward controlling the entire Slavyansk-Kramatorsk fortified area and declared that Russia now controlled all of the Luhansk region [5, 2, 3, 6]. The Kremlin views Kostiantynivka as a key defensive hub and logistics center vital to Ukrainian defense in Donetsk [1, 5, 7, 8, 6].
However, Ukraine's General Staff and President Volodymyr Zelensky denied the Russian claim, insisting that Kostiantynivka remains under Ukrainian control and that defensive operations continue in the area [9, 5, 7, 10, 6]. A Ukrainian military official dismissed the Russian announcement as "more fake claims," while Zelensky called it "just another Russian lie" and suggested that if the city were under Russian control, Putin would be willing to meet for diplomatic talks there [9, 7].
Following these events, Ukraine launched drone strikes on Russian territory including Saint Petersburg on July 4 amid ongoing hostilities [11, 6]. Russian authorities said nearly 400 drones were used in attacks on over a dozen Russian regions [11]. Saint Petersburg's governor Alexander Beglov said air defenses shot down 72 drones there with no casualties or damage [11]. Putin warned that Ukrainian strikes on Russian civilian infrastructure justify expanding border security zones and continued large-scale Russian military operations [2, 3, 4, 6].
The US issued warnings of potential Russian provocations against NATO member Poland amid increasing tensions along the alliance's eastern flank [6]. On July 3, a Russian strike on the Ukrainian city of Sumy killed four people, including a child [11]. Recent Russian airstrikes on Kyiv caused at least 30 deaths and injured over 90 others [5, 2, 3, 6].
Fighting over Kostiantynivka remains contested, with Russia reporting partial control over recent weeks and Ukraine denying overall loss of the city. The next major developments are expected as both sides continue to battle for control in eastern Ukraine.
