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 wintersets in.

The failed test launch would have taken place two days before President Joe Biden arrived in Ukraine's capital, Kyiv, on an unannounced trip, as he made his way to Poland to meet with NATO allies and to give a speech marking a year of war.
Ukrainian officials on Sunday publicly claimed Russia was preparing to stage large scale nuclear exercises including a launch to coincide with Biden's trip.

Putin's decision was announced on Tuesday as he gave an annual state-of-the-union speech in Moscow, days ahead of the one-year anniversary of the invasion into Ukraine.

That will be interpreted as a veiled threat in relation to the war in Ukraine -- experts have feared Russia might conduct a nuclear bomb test to intimidate Kyiv and its Western allies. Putin ordered Russia’s military to prepare the possibility to hold a test.
“Some actors in Washington are thinking about testing nuclear weapons,” he said. “The defense ministry and RosAtom must prepare also to conduct nuclear tests in case of necessity. But Russia will not conduct it first.”
