Russia-Ukraine War: What to know as Ukraine resists advance
By The Associated Press
The Russian military assault on Ukraine went into its fifth day after Russian President Vladimir Putin ordered his nuclear forces put on increased alert, ratcheting up tensions yet further. There was a tense calm in the Ukrainian capital of Kyiv, but explosions and gunfire were heard in embattled cities in eastern Ukraine as Russian troops met unexpectedly stiff resistance. A Ukrainian delegation held talks with Russian officials at the border with Belarus, though they ended with no reported agreements aside from plans for further talks. Western sanctions triggered by the invasion sent the ruble plummeting, so ordinary Russians flocked to banks and ATMs to draw out cash. Ukrainian families huddled in underground subway stations for yet another night as air sirens howled.
