Russian forces are continuing their attempted push through Ukraine from multiple directions, while Ukrainians, led by President Volodymyr Zelenskyy, are putting up “stiff resistance,” according to U.S. officials.

The attack began Feb. 24, when Russian President Vladimir Putin announced a “special military operation.”

Russian forces moving from neighboring Belarus toward Ukraine’s capital, Kyiv, don’t appear to have advanced closer to the city since coming within about 20 miles, although smaller advanced groups have been fighting gun battles with Ukrainian forces inside the capital since at least Friday.
