Key City's Fate In Balance As Fighting Rages In East Ukraine

The plodding battle for Sievierodonetsk has devolved into street-to-street fighting that has been relatively rare.

Russian forces pounded an eastern Ukrainian city Thursday and the two sides waged pitched street battles that Ukrainian President Volodymyr Zelenskyy said could determine the fate of the critical Donbas region.

Meanwhile, Russia claimed that it struck a training facility far from the front lines, west of the capital.

In the wake of a series of setbacks in the three-month-old war, Russia set its sights on the industrial Donbas region of coal mines and factories, where Moscow-backed separatists have been fighting Ukrainian troops for years and where they already held swaths of territory before the invasion.
