Russia now controls more than two-thirds of Ukraine’s Donetsk region — the main theater of the ground war. Russian forces have carved out a 10-mile-deep pocket around the Ukrainian troops defending the crucial city of Kostiantynivka, partly surrounding them from the east, south and west.

The European Union and Britain are ramping up pressure on Russia over its war on Ukraine. The EU has introduced new sanctions to deprive Moscow of energy revenue through a lower oil price cap and a ban on transactions with Nord Stream gas pipelines.
