Russia tries to make sudden advance in Ukraine before Trump-Putin summit

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

Ukraine's authoritative DeepState war map showed on Tuesday that Russian forces had advanced by at least 10 km (six miles) north in two prongs in recent days, part of their drive to take full control of Ukraine's Donetsk region.
