Almost a year after Russian President Vladimir Putin launched a full-scale invasion of neighboring Ukraine, the two countries are engaged in a struggle for control of areas throughout the east and south.

Putin's forces pulled out of key positions in November, retreating from Kherson as Ukrainian troops led a counteroffensive targeting the southern port city. Russian drones have continued bombarding civilian targets throughout Ukraine, knocking out critical power infrastructure as winter sets in.

Russia targets Ukraine's energy infrastructure

Air raid sirens went off in Kyiv for more than three hours on Tuesday, as Russia launched a wave of strikes targeting energy infrastructure across Ukraine.

At least three incoming strikes were confirmed by the authorities in Kyiv. A power plant on the city's left bank was hit, knocking out power for some residents in that area. Some locals said they didn't have running water.

Kyiv officials did not say whether there were casualties. It was also unclear whether the plant was hit by a missile or a drone -- both types of weapons were reportedly heading towards Kyiv, but some were shot down.
