President Vladimir Putin said he'd sought an "open dialogue" with the West.
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.

At least 19 people have died since Russian missiles struck civilian and critical infrastructure targets across Ukraine on Monday, according to the Ukrainian State Emergency Service.
Another 105 people were injured in the attacks in over a dozen Ukrainian regions, including the capital Kyiv, where more than 30 fires broke out.
Ukrainian President Volodymyr Zelenskyy on Monday said Russia's missile assault on civilian targets across Ukraine showed Russia's "true face."
Eleven people have died and 64 are hurt across eight oblasts and the city of Kyiv, according to the Ukrainian State Emergency Service.
"The world once again saw the true face of a terrorist state that is killing our people," Zelenksyy said on Twitter. "On the battlefield & in peaceful cities. A country that covers its true bloody essence & goal with talks about peace. It proves that the liberation of is the only basis of peace & security."
Russian President Vladimir Putin said Monday’s attacks on civilian areas across Ukraine were a response to Saturday’s attack on the bridge connecting Russia and Crimea.
“To leave without an answer a crime of such a type is already simply impossible. This morning, at the proposal of Russia’s ministry of defense and general staff, a massive strike of high precision, long-range weapons has been delivered from air, land and sea, on Ukraine's energy facilities, military command and communication,” Putin said.
He added, “In the case of continuing terrorist attack on our territory, the answers from Russia will be severe and by their scale correspond to the level of threat created for the Russian Federation. No one should have any doubts about that.”

The U.S. Embassy in Kyiv emailed Americans in Ukraine, warning that they should shelter in place.
"The U.S. Embassy urges US citizens to shelter in place and depart Ukraine now using privately available ground transportation options when it is safe to do so," the email said.
