Escalating battle for city comes as overnight Russian drone and missile strikes kill six people, including two children, age 11 and 14

Ukraine has deployed special forces to the embattled eastern city of Pokrovsk in an attempt to push back an intense Russian assault involving thousands of troops, Kyiv’s top commander has said.

The escalating battle in the strategically important city comes as an overnight wave of Russian drone and missile attacks on Ukraine killed six people, including two children, and cut power to tens of thousands, officials said on Sunday.
