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.

Evacuations underway in Ukraine after dam was targeted by Russian missiles
Evacuations are underway in two districts in the Ukrainian town of Kryvyi Rih after Russia struck a nearby dam with eight cruise missiles.
The strikes badly damaged the dam and a nearby pumping station, releasing huge amounts of water into the Inhulets River and causing it to swell and break its banks. Streets and homes were flooded and two bridges were swept away.
Kryvyi Rih is the hometown of Ukrainian President Volodymyr Zelenskyy. About 650,000 people live there.
"Your missile attacks today, Russian missiles targeting Kryvyi Rih, the dam of the Karachunivske Reservoir, the objects that have no military value at all, in fact hitting hundreds of thousands of ordinary civilians, is another reason why Russia will lose. And not just this war, but history itself," Zelenskyy said in his evening address Wednesday.
