Russia-Ukraine war: counteroffensive not yet launched, says senior official; UK ‘cannot yet say Russia responsible for dam destruction’ –as it happened

Secretary of Ukraine's National Security and Defence Council dismisses claim counteroffensive has begun; Rishi Sunak says UK can't say definitively' whether Russia was responsible

• People in Ukraine: do you live near the Nova Kakhovka dam?

Neither the French, US or British representatives at the UN directly said there was evidence of Russian responsibility, but called for an investigation and insisted their support for Ukraine was unwavering.

Outside the UN security council chamber on Tuesday, the deputy US ambassador to the UN, Robert Wood, said: We're not certain at all, we hope to have more information in the coming days.
