Moscow's forces are making gains near Pokrovsk in Ukraine's Donetsk region, according to the Institute for the Study of War.

Russian forces have made a sudden thrust into eastern Ukraine near the coal mining town of Dobropillia, a move that may be designed to increase the pressure on Kyiv to cede land as the U.S. and Russian presidents prepare to meet.

President Trump says he expects to know quickly if a deal can be made with Russian leader Vladimir Putin to halt the war in Ukraine.
