Seven people – including a 23-day-old baby girl – were killed in Russian shelling in Ukraine's southern Kherson region on Sunday, the country's Internal Affairs Ministry said.

Artillery shelling in the village of Shiroka Balka, on the banks of the Dnieper River killed a family — a husband, wife, 12-year-old boy and 23-day-old girl — and another resident.

Two men were killed in the neighboring village of Stanislav, where a woman was also wounded.

The attack on Kherson province followed Ukrainian Deputy Defense Minister Hanna Maliar's comments on Saturday attempting to quell rumors that Ukrainian forces had landed on the occupied left (east) bank of the Dnieper in the Kherson region.

 "Again, the expert hype around the left bank in the Kherson region began. There are no reasons for excitement," she said.

Kherson regional Gov. Oleksandr Prokudin said Sunday that three people had been wounded in Russian attacks on the province on Saturday.

Ukrainian military officials said Saturday evening that Kyiv's forces had made progress in the south, claiming some success near a key village in the southern Zaporizhzhia region and capturing other unspecified territories.

Ukraine's General Staff said they had "partial success" around the tactically important Robotyne area in the Zaporizhzhia region, a key Russian strongpoint that Ukraine needs to retake in order to continue pushing south towards Melitopol.

"There are liberated territories. The defense forces are working," General Oleksandr Tarnavskyi, commander of Ukraine's southern forces, said of the southern front.

Last week, Russia launched two hypersonic missiles in the Donetsk region that damaged an apartment building and a hotel popular with international journalists covering the war. Pavlo Kyrylenko, head of the regional military administration in the Donetsk region, told CBS News that seven people were killed in the Monday evening strike with 81 more wounded, including two children.

Almost half of those wounded in that attack were Ukrainian fire and rescue workers, as the second missile struck about 40 minutes after the first. Emergency services rushed to the site of the first explosion, not knowing that a second missile was about to hit. 

Battles in recent weeks have taken place on multiple points along the over 1,000-kilometer (600-mile) front line as Ukraine wages a counteroffensive with Western-supplied weapons and Western-trained troops against Russian forces who invaded nearly 18 months ago.

Ukrainian troops have made only incremental gains since launching a counteroffensive in early June.

In Russia, local officials reported on Sunday that air defense systems shot down three drones over the Belgorod region and one over the neighboring Kursk region, both of which border Ukraine.

Ukrainian drone strikes on Russian border regions are a fairly regular occurrence. Drone attacks deeper inside Russian territory have been on the rise since a drone was destroyed over the Kremlin in early May. In recent weeks, attacks have increased both on Moscow and on Crimea, which Russia annexed from Ukraine in 2014 — a move that most of the world considered illegal.

Firing drones at Russia, after more than 17 months of war, has little apparent military value for Ukraine but the strategy has served to unsettle Russians and bring home to them the conflict's consequences.

The Wagner mercenary group has played a key role in Russia's military campaign, but there is a "realistic possibility" that the Kremlin is no longer providing funding, according to British defense officials.

In its latest intelligence briefing, the Ministry of Defense said it believed Wagner was "likely moving towards a down-sizing and reconfiguration process" in order to save money, and that the Kremlin had "acted against some other business interests" of Wagner chief Yevgeny Prigozhin. The officials assessed that Belarusian authorities were the "second most plausible paymasters."

Thousands of Wagner fighters arrived in Russian-allied Belarus under a deal that ended their armed rebellion in late June and allowed them and Prigozhin to avoid criminal charges.
