The Ukrainian side has circulated a video showing Russian troops constructing an underground tunnel, likely near Kostiantynivka in eastern Ukraine. Kyiv believes the tunnel is intended for covert infantry movement and to improve connectivity of Russian positions. The video has heightened Ukrainian concerns about tunnel warfare following the Russian pipe operation in Avdiivka and the 'Potok' operation in Sudzha.
