Russia fired six cruise missiles at the southern port city of Odesa Saturday, according to Ukraine's Security and Defense Force South.
Video from the city shows thick columns of black smoke in several locations.
The enemy continues not only the physical destruction of the region's infrastructure, but also the psychological pressure on the civilian population," said the Ukrainian military's Operational Command (South).
It said there were no casualties.
The regional military administration also posted a drone video purporting to show a strike against a Russian patrol boat in the Black Sea.
Some background: In the last few days, Ukrainian air force units have carried out several strikes against Russian positions on Russian-occupied Snake Island off the coast of Crimea.
On Tuesday, the Ukrainian Armed Forces said they hit at least two Russian military positions there using a Bayraktar UAV, a military drone.
Meanwhile, the UN World Food Programme has called for the reopening of ports in Odesa to help rein in the global hunger crisis.
