A group of men swing a pole into the rising waters, trying to save wooden planks floating in the current that has submerged streets in the city of Kherson following damage to a Russian-occupied dam in Ukraine. "The water has risen to two metres and continues to rise," a local man named Denis tells AFP, adding that his friends and him have been "trying to at least salvage something." Moscow and Kyiv have blamed each other for the damage to the Kakhovka hydroelectric dam, which was seized at the start of the Russian offensive in Ukraine and notably supplies water to the Crimean peninsula, annexed by Russia in 2014.
