Russian forces tried Monday to press their offensive deeper into eastern Ukraine after taking control of a key stronghold.
The Ukrainian military confirmed that its forces had withdrawn from the city of Lysychansk, the last bulwark of Ukrainian resistance in the Luhansk province, one of the two regions that make up the country's eastern industrial heartland of Donbas. The Russians also control about half of Donetsk, the second province of Donbas.
