Russia-Ukraine updates: Putin suspends key US-Russia nuclear treaty in speech denouncing West
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.

Russia claims withdrawal from grain deal is due to 'terrorist attack' in Black Sea
Russia claims that its withdrawal from the U.N.-brokered grain deal was a response to a drone attack Saturday in the waters of the Sevastopol Bay, in the Black Sea near Crimea.
"The Ukrainian armed forces, under the cover of a humanitarian corridor created as part of the implementation of the 'Black Sea Initiative' to export Ukrainian agricultural products, launched massive air and sea strikes using unmanned aerial vehicles against the ships and infrastructure of the Russian Black Sea Fleet at the naval base in Sevastopol," the Russian Foreign Ministry said in a statement.
Russia claimed the drones did not cause serious damage to infrastructure and that the Black Sea Fleet destroyed all the drones.
Russia accused British specialists of being involved in preparing the attack and training the Ukrainian military in the city of Ochakov.
"According to available information, representatives of this unit of the British Navy took part in the planning, support and implementation of a terrorist act in the Baltic Sea on September 26 this year to undermine the Nord Stream 1 and Nord Stream 2 gas pipelines," the Russian military claimed.

Russia blames UK for Nord Stream blasts
Russia accused the British army of carrying out a "terrorist act" in the Baltic Sea to undermine the Nord Stream 1 and Nord Stream 2 gas pipelines on Sept. 26.
"According to available information, representatives of this unit of the British Navy took part in the planning, provision and implementation of a terrorist act in the Baltic Sea on September 26 this year to undermine the Nord Stream-1 and Nord Stream-2 gas pipelines," the Ministry of Defense said in a statement.
The British Ministry of Defense denied the accusation calling it an "invented story."
"To detract from their disastrous handling of the illegal invasion of Ukraine, the Russian Ministry of Defence is resorting to peddling false claims of an epic scale. This invented story, says more about arguments going on inside the Russian Government than it does about the west," the British Ministry of Defense said in a statement on Twitter.
