The Ukrainian city of Sumy is near the Russian border, but far from the current front. Russia has amassed tens of thousands of troops in the region and occupied several villages. Could a greater incursion be coming?

Russian forces are advancing in the northern Ukrainian region of Sumy, bringing the regional capital within range of their drones and artillery, according to Ukrainian officials and analysts.

The advance towards the city of Sumy - the administrative center of the Sumy region - comes as Kyiv showed its ability to continue fighting by conducting a series of strikes in recent days, hitting Russian strategic bombers and the Crimean Bridge.
