Ukraine touts ground gains as Russia states intent to hold elections in occupied areas

Russia announced plans Thursday to stage elections in occupied parts of Ukraine in just three months, Moscow's latest bid to signal that it is in control, even as a Ukrainian counteroffensive has pushed its forces back in some areas.

The Ukrainian assault is in its early stages, and military experts say the decisive battles still lie ahead. But corpses of Russian soldiers and burnt-out armoured vehicles lining roads in villages newly recaptured by Ukrainian troops attested to Kyiv's biggest advances since last year.

"Our heroic people, our troops on … the front line are facing very tough resistance," Ukrainian President Volodymyr Zelenskyy told NBC News in Kyiv.

"Because for Russia to lose this campaign to Ukraine, I would say, actually means losing the war."

Also Thursday, Zelenskyy urged the Swiss parliament in a video address to allow other states to re-export Swiss-made weapons to Ukraine.

Reuters reached the villages of Neskuchne and Storozheve over the past two days, providing the first independent confirmation of the Ukrainian advance several kilometres south along the Mokry Yali river.

Several bodies of Russian soldiers lay in the streets of ruined and depopulated villages. Ukrainian troops in Storozheve told Reuters they killed around 50 Russians and captured four there.

The Ukrainian military, which had maintained strict silence about the campaign, came forward to tout the gains on Thursday.

Troops captured at least seven settlements and 100 square kilometres of territory in two major pushes in the south so far, Brigadier-General Oleksii Hromov said.

"We are ready to continue fighting to liberate our territory even with our bare hands," he said.

The army on the southern front had advanced in the area along the Mokry Yali, as well as on another axis further west near the village of Mala Tokmachka, officials said.

They described advances in the east around the ruined city of Bakhmut, which Moscow seized last month.

Russian President Vladimir Putin insisted this week that Moscow's goals in Ukraine remain unchanged. He claimed that Russian forces were inflicting 10 times more casualties on Ukrainians than they were enduring.

African leaders whose countries have been hit hard by the fallout from the war are set to attempt to mediate in the conflict.
