Ukraine faces ‘toughest winter’ since Russia’s full-scale invasion, UN official tells BBC

Speaking in Ukraine, De Croo – the UN's third most senior official – accused Russia of systematically targeting the country's energy infrastructure.

Under efforts to prepare Ukraine for winter the UN Development Programme is helping to rebuild parts of its energy system that were damaged last winter.

Two people were also killed earlier this week when Russian drones hit a border crossing between Ukraine and Moldova, which has increasingly found itself caught up in the conflict.
