Russia’s Defence Ministry accused Ukraine on Sunday of rejecting a proposed six-hour ceasefire in and around the eastern city of Kostiantynivka. Moscow stated the ceasefire was intended to allow for the handover of bodies of fallen Ukrainian soldiers. Russia claimed it had given Kyiv until 0900 GMT on Sunday to respond to the proposal.

The dispute over Kostiantynivka marks the latest exchange in an ongoing information war between the two nations. Russia had previously announced on Friday that its forces had captured the city, a key objective in its advance through the Donetsk region. Ukraine has vehemently denied this claim, asserting that its troops remain in control of the area.

Ukrainian President Volodymyr Zelenskyy dismissed the Russian claim as "another Russian lie," suggesting that if Kostiantynivka were under Russian control, there would be no impediment for a diplomatic meeting with Russian President Vladimir Putin to end the war. He characterized the Russian assertion as an attempt to fabricate a news narrative.

Kremlin spokesman Dmitry Peskov, responding to Zelenskyy’s remarks, mockingly stated that Kostiantynivka was already considered part of Russia. He reiterated the Kremlin's standing invitation for Zelenskyy to meet President Putin in Moscow, a proposal Zelenskyy has previously rejected, preferring talks outside the Russian capital.

In separate developments, Russian officials reported that one person was killed and two others injured in a Ukrainian attack on Russian-occupied Crimea early Sunday. The Kremlin-installed regional Governor Sergei Aksyonov provided these details on Telegram, without elaborating on the specifics of the attack.

These recent events follow diplomatic engagements involving Ukrainian and Russian leadership. Both President Zelenskyy and President Putin reportedly spoke with former U.S. President Donald Trump regarding efforts to end the conflict, which has now entered its fifth year. According to Kremlin aide Yury Ushakov, Trump offered assistance in finding a resolution to the war during a Saturday phone call.

President Zelenskyy also confirmed his conversation with Trump, stating that their discussion included the extensive 1,200-kilometer (745-mile) front line. The timing of these conversations occurs ahead of a significant NATO summit scheduled to take place in Ankara.

The contested control of Kostiantynivka highlights the broader strategic importance of the Donetsk region in the ongoing conflict. Both sides continue to vie for territorial gains, with control over key cities and towns serving as crucial objectives in their respective military campaigns.
