Vladimir Putin’s warplanes have dropped “explosive objects” into the paths of civilian shipping lanes in the Black Sea, the region’s military command said. “The occupiers are continuing to terrorise the paths of civilian shipping in the Black Sea with tactical aviation, dropping explosive objects into the likely paths of civilian vessel traffic,” it said. “There were three such drops registered in the last 24 hours. However, the navigation corridor continues to function under the watch of the defence forces.” Ukraine is trying to build up a new shipping lane without Russian approval to revive its vital seaborne exports. But Russia said it would consider any vessel a potential military target after it quit UN-brokered deal allowing Ukrainian goods to pass through. It comes as Ukrainian troops have made confirmed advances against Russia on two fronts, according to the Institute for the Study of War. “Geolocated footage posted on 30 October shows that Ukrainian forces have advanced northeast of Kurdyumivka (10km southwest of Bakhmut),” it said. Ukrainian forces have also “marginally advanced” west of Robotyne, Zaporizhzhia, according to geolocated footage seen by the think tank.
