Videos posted on social media – and geolocated by CNN – shows thick black smoke rising not far from a railway station in the town of Oktyabrskoye in the center of Crimea. There has also been a wider escalation in the Black Sea area, with Russia pulling out of a crucial grain deal and for several nights pounding the southern city of Odesa. It marks the latest in a series of recent strikes on Russian supplies and critical infrastructure in the occupied peninsula, which Ukraine ultimately wants to recapture. Ukrainian forces hit an ammunition dump in Crimea, forcing an evacuation of the area and canceling train services, authorities in the annexed province say.
