KYIV—Intense fighting between Ukrainian and Russian forces raged in the streets of the industrial city of Sievierodonetsk on Monday in a pivotal battle for advantage in eastern Ukraine, the provincial governor said.
The Ukrainian defenders had over the weekend regained control over about half the city just as the Russians appeared on the verge of victory.
But their position had again become more perilous on Monday morning, Luhansk governor Serhiy Gaidai told state television.
“Our defenders managed to undertake a counter-attack for a certain time, they liberated almost half of the city. But now the situation has worsened a little for us again,” Gaidai said….
