Melitopol Mayor Ivan Fedorov said on Telegram that two explosions occurred in the Russian-occupied Melitopol on the evening of Dec. 19.
The Russian-state-controlled RIA news outlet also reported the explosions.
Located in Ukraine's southeastern Zaporizhzhia Oblast, Melitopol has been occupied by Russia since March.
Russian and Ukrainian forces recently engaged in artillery-on-artillery “counterbattery” around Huliaipole and Polohy, around 100 kilometers north of Melitopol, in a sign that Ukraine’s fourth counteroffensive might be imminent, Forbes reported.
Earlier on Dec. 12, Melitopol Mayor Ivan Fedorov reported that a bridge near Melitopol, used by the Moscow troops for transporting military equipment, had exploded.
