Ukraine wary of Putin's ceasefire proposal in Kostiantynivka

Ukraine has expressed concern over Vladimir Putin's proposal for a temporary ceasefire in Kostiantynivka, fearing Russia may use it to strengthen its military positions. The proposal comes as Ukraine appears to be losing ground in the city. The Russian president suggested a five-day humanitarian ceasefire to evacuate civilians and clear mines, a plan reportedly backed by the US after American envoys met with Putin and Zelenskyy. Ukraine's skepticism stems from a previous ceasefire in Olesjky, where Russia allegedly used the pause to bring in heavy weapons. Military expert Johan Huovinen doubts the ceasefire would provide Russia significant military advantage, noting the operation would be limited to a small corridor. Russia began attacking Kostiantynivka in November 2025, with the New York Times warning the city could become another Bakhmut.
