Ukraine has used its pioneering naval drones to hit Russian targets like expensive warships. Now it has a growing fleet designed to fight on rivers.

A historic theater in the Russian-occupied Ukrainian city of Mariupol has opened its doors more than three years after it was pummeled in a Russian airstrike that killed hundreds of civilians sheltering inside.

Heavy fighting is ongoing in Rodynske in the Donetsk region. However, information about Russian forces' complete control of the city does not correspond to reality, according to a report by Operational Command East.

Ukraine said a resistance agent was able to sneak into a Russian hangar and destroy two Russian fighter jets.

The incident took place in the same area of the Russian capital where Lt. Gen. Fanil Sarvarov was killed by a car bomb on Monday morning.

Two Russian soldiers shot dead seven civilians who were hiding in the basement of a residential building. The crime took place on December 21 in Pokrovsk, Donetsk region, according to the I Want to Live project of the Coordination Headquarters for the Treatment of Prisoners of War.

NATO countries neighboring Ukraine are being compelled to respond militarily in defense of alliance territory.

A Russian general was killed when a bomb detonated under his car in Moscow and investigators said Ukraine​ could be behind the attack.
