Russian forces set their sights on their next objectives in Ukraine's eastern Donetsk province on Tuesday after President Vladimir Putin claimed victory in neighboring Luhansk province and the five-month long war entered a new phase.

Serhiy Gaidai, the Ukrainian governor of Luhansk, said Ukrainian forces that retreated from Lysychansk were now holding the line between Bakhmut and Sloviansk, preparing to fend off a further Russian advance.

Reuters could not verify the battlefield accounts.

Ukraine's hopes for a sustained counter-attack rest in part on receiving additional weapons from the West, including rockets that can neutralize Russia's huge firepower advantage by striking deep behind the front line.
