Deadly Russian shelling was reported in Ukraine's east and south.

The governor of the eastern region of Luhansk, Serhyi Haidai, said Russia launched over 20 artillery, mortar and rocket strikes in the province overnight and its forces were pressing toward the border with the Donetsk region.?

“We are trying to contain the Russians' armed formations along the entire front line,” Haidai wrote on Telegram.

Last week, Russia captured the last major stronghold of Ukrainian resistance in Luhansk, the city of Lysychansk. Analysts predicted Moscow's troops likely would take some time to rearm and regroup.?

But “so far, there has been no operational pause announced by the enemy. He is still attacking and shelling our lands with the same intensity as before,” Haidai said. In a later post, he claimed Russian bombardment of Luhansk was suspended because Ukrainian forces had destroyed ammunition depots and barracks used by the Russians.

Ukraine's deputy prime minister, Iryna Vereshchuk, appealed to residents of Russian-held territories in the south to evacuate so the occupying forces could not use them as human shields during a Ukrainian counteroffensive.

“You need to search for a way to leave, because our armed forces are coming to de-occupy," she said. “There will be a massive fight. I don't want to scare anyone. Everyone understands all of this anyway.”

Speaking at a news conference late Friday, Vereshchuk said a civilian evacuation effort was underway for parts of the Kherson and Zaporizhzhia regions. She declined to give details, citing safety considerations.?

It was not clear how civilians were expected to safely leave Russian-controlled areas while missile strikes and artillery shelling continue in surrounding areas, or whether they would be allowed to depart or even hear the government's appeal.?

The war's death toll continued to rise.?

Five people were killed and eight more wounded in Russian shelling Friday of Siversk and Semyhirya in Donetsk province, its governor, Pavlo Kyrylenko, wrote Saturday on his Telegram channel.

In the city of Sloviansk, named as a likely next target of Russia's offensive, rescuers said they pulled a 40-year-old man from the rubble of a building destroyed by shelling Saturday. Kyrylenko said multiple people were under the debris.

Russian missiles also killed two people and wounded three others Saturday in the southern city of Kryvyi Rih, according to regional authorities.

“They deliberately targeted residential areas,” Valentyn Reznichenko, governor of the eastern Dnipropetrovsk region, asserted on Telegram. Kryvyi Rih's mayor, Oleksandr Vilkul, asserted on Facebook that cluster munitions had been used and urged residents not to approach unfamiliar objects in the streets.

In northeast Ukraine, a Russian rocket strike on Saturday hit the center of Ukraine's second-largest city, Kharkiv, injuring six people, including a 12-year-old girl, authorities said.

“An Iskander ballistic missile was probably used in the strike," the Kharkiv Regional Prosecutor's office said. "One of the missiles hit a two-story building, which led to its destruction. Neighboring houses were damaged.”?

The city has been targeted throughout the war, including several times in the past week. As survivor Valentina Mirgorodksaya dabbed at a cut on her cheek, first responders warily inspected the building shattered in Saturday's strike.?

“I don't know,” Mirgorodksaya said. “I just don't know.”

Mykolayiv Mayor Oleksandr Senkevych reported in a Telegram post that six Russian missiles were fired at his city in southern Ukraine, near the Black Sea, but caused no casualties.?

Russian defense officials claimed Saturday that their forces destroyed a hangar housing U.S. howitzers in Ukraine, near the Donetsk province town of Chasiv Yar. There was no immediate response from Ukraine.
