Russian Defense Ministry spokesperson, Igor Konashenkov, said that among the targets hit were four command posts, 57 assembly points of Ukrainian forces, and military vehicles and equipment.

He also referred to the elimination of about 40 Ukrainian targets, and the destruction of 7 military vehicles, as a result of targeting points in the Novorontsova and Kislyovka regions, with high-precision missiles.

In addition, the ministry claimed that the Air Defense Forces had shot down six drones and had intercepted two "Tochka-O" missiles in the Donetsk region.

These strikes came after the ministry announced yesterday, Tuesday, that it had started a new phase of military operations in eastern Ukraine to liberate Donetsk and Luhansk republics, referring to the two regions controlled by pro-Moscow rebels.

Russian Foreign Minister Sergey Lavrov described this stage as very important amid Western and Ukrainian expectations that these areas would witness violent fighting between the Russians and the Ukrainians.

Since its withdrawal from the vicinity of the capital Kyiv, at the beginning of April, the Russian forces announced that they would shift their operations to eastern Ukraine, which is of great importance to Moscow. Still, the zero hour did not seem to start until two days ago.

Eastern Ukraine, especially the Donbas region, is vital for the Russians. Controlling would enable Moscow to move at ease between those regions and the south, specifically the Crimea peninsula, annexed to Russia in 2014. Russia has based one of its four fleets in the Crimean peninsula which would help it consolidate its power over the black sea region.
