Retreating Russian forces have partially destroyed a dam near the city of Kherson, a sabotage that environmentalists had warned could flood downstream towns and villages.A black and white video uploaded onto the website of the pro-war Russian newspaper Izvestia showed the moment a huge blast hit the Nova Kharkova dam.Benjamin Strick, a London-based open-source investigator who has previously worked for Bellingcat, highlighted the destruction of two other road bridges that cross the Dnipro River as well as the Nova Kharkov dam, which lies 35 miles upstream from Kherson.The satellite photos of the two other road bridges, the Antonovsky Bridge in Kherson and a bridge near the village of Darivka, clearly showed gaping holes along them but the satellite photos of the dam showed damage to only one end.This week as many as 30,000 Russian soldiers completed their withdrawal from the right back of the Dnipro River after the Russian ministry of defence said that it had become too hard to resupply them."
