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 now out of Iranian-made drones, Western officials say
According to Western officials, Russia has run out of Iranian-made drones. Russia had been using the lethal drones, along with missiles, in a wave of aerial bombardments on Ukrainian infrastructure over a period of several weeks.
But, the drones have been absent in recent Russian attacks. A western official said the Russians "anticipate a resupply."
In light of Ukraine’s apparent drone attacks on military airbases deep inside Russia, Western officials said Russia will now be undergoing "a significant amount of soul-searching" over their ability to defend significant military assets deep inside Russia’s borders.
The official, who characterized the attacks as "an egregious failure of security" said the Russian military’s potential had been consistently overestimated by the west.
“I no longer think the Russians are ten-feet tall," the official said.
