What did 7 September 2023 show about a war of many fronts?
A retrospective on the day Ukrainian forces entered two border villages in Kharkiv Oblast, as aid, diplomacy and a deadly market strike shaped the days around it.
What did the war look like on 7 September 2023? It did not offer a single decisive story. On that date, Ukrainian forces entered the deserted villages of Stroivka and Topoli at the Russia–Ukraine border in Kharkiv Oblast. Russia had abandoned both villages after the 2022 Kharkiv counteroffensive, but Ukraine had previously been unable to enter them because of mines in the area.
The detail matters as a reminder of how slowly ground is regained. Ground that had been left behind for months could not simply be walked into; the mines had kept it out of reach.
A week of aid and losses
The days just before 7 September carried several developments. On 6 September, the United States announced a $175 million aid package for Ukraine. It included depleted uranium ammunition for the first time, intended for use with Abrams tanks.
The same day, British Defence Secretary Grant Shapps confirmed reports from Russian officials that a Challenger 2 tank had been destroyed in Ukraine. It was the first loss of that model on the battlefield.
Also on 6 September, Russian pilot Maxim Kuzminov, who had defected to Ukraine with a Mi-8 helicopter, received a $500,000 reward for defecting.
Civilian toll in Kostiantynivka
The gravest event of the period was the missile strike on a marketplace in Kostiantynivka, Donetsk Oblast, on 6 September. At least 15 people were killed and about 30 others injured. Kyiv blamed Russia, which denied involvement. An investigation by the New York Times found evidence suggesting that a Ukrainian 9M38 missile fired by a mobile Buk antiaircraft vehicle was responsible.
Later accounts added detail: the dead included a child and a couple in their 50s who had been selling flowers at the market. A spokesman for the Security Service of Ukraine said the official investigation was continuing, but that the service believed the weapon was an S-300 missile launched by Russian forces.
Diplomacy and the Black Sea
On 6 September, Russian President Vladimir Putin and Turkish President Recep Tayyip Erdoğan held talks in Sochi on reviving the Black Sea Grain Initiative, which would enable grain to cross the Black Sea. That agreement had been signed in Istanbul on 22 July 2022 by Russia, Ukraine, Turkey and the United Nations, set up a joint coordination and inspection centre in Turkey, and was meant to address a worldwide food crisis after the invasion halted Ukraine's maritime grain exports.
The sea itself remained a combat zone. On 5 September, Russia's defence ministry said it had repelled a Ukrainian aerial drone attack over the Black Sea and destroyed four Ukrainian military boats carrying troops towards Cape Tarkhankut on the Crimean coast. It also said it had shot down three Ukrainian drones over Istra, Moscow, and the Kaluga and Tver regions near Moscow.
Spillover beyond the front
The war's effects reached other countries too. On 6 September, Romania's Ministry of National Defence confirmed that debris from a Russian drone had been found on Romanian territory in Tulcea County, while Romania denied claims that drones launched by Russia had exploded on its territory.
On 5 September, Cuba's foreign ministry said criminal proceedings had been started against a recruiting group seeking mainly to enlist Cuban citizens residing in Russia to fight in Ukraine. It noted that mercenary activity was prohibited in Cuba and reiterated that the country was not part of the war.
What the day showed
Taken together, 7 September 2023 and the days around it show a conflict fought through mines, munitions, drones, diplomacy and contested accounts of who fired on civilians. The border villages in Kharkiv Oblast were a modest gain, set against a week in which the cost to civilians and the question of Black Sea trade stayed in view.
