Gunmen shot dead 11 people at a Russian military training ground on Saturday, the defence ministry said, in the latest blow to President Vladimir Putin’s forces since the invasion of Ukraine.

RIA news agency cited the ministry as saying 15 others were wounded in the shooting, in Russia’s southwestern Belgorod region that borders Ukraine, when two men gunned down a group who had volunteered to take part in the war.

It said the two assailants — nationals from an unspecified former Soviet republic — had been shot dead. Some Russian independent media outlets reported that the number of casualties was higher than the official figures.

“A terrible event happened on our territory, on the territory of one of the military units,” the governor of Belgorod region Vyacheslav Gladkov said early on Sunday.

“Many soldiers were killed and wounded … There are no residents of the Belgorod region among the wounded and killed,” Gladkov said in a video post on the Telegram messaging app.

The attack took place a week after a blast damaged a bridge in Crimea, the peninsula annexed by Russia from Ukraine in 2014. Earlier in the war, Russia’s flagship in the Black Sea blew up and sank.

“During a firearms training session with individuals who voluntarily expressed a desire to participate in the special military operation [against Ukraine], the terrorists opened fire with small arms on the personnel of the unit,” RIA cited a defence ministry statement as saying.

Mobilisation

Just a day earlier, Putin said Russia should be finished calling up reservists in two weeks, promising an end to a divisive mobilisation that has seen hundreds of thousands of men summoned to fight in Ukraine and huge numbers flee the country.

Oleksiy Arestovych, an adviser to Ukrainian President Volodymyr Zelenskiy, said in a YouTube interview that the attackers were from the Central Asian nation of Tajikistan and had opened fire on the others after an argument over religion.

Tajikistan is a predominantly Muslim nation, while around half of Russians follow various branches of Christianity. The Russian ministry had said the attackers were from a nation in the Commonwealth of Independent States, which groups nine ex-Soviet republics, including Tajikistan.

Reuters was not immediately able to confirm the comments by Arestovych, a prominent commentator on the war, or independently verify casualty numbers and other details of the incident.

Elsewhere, Zelenskiy said that Ukrainian troops were still holding the strategic eastern town of Bakhmut despite repeated Russian attacks while the situation in the larger Donbas region remained very difficult.

Russian forces have repeatedly tried to seize Bakhmut, which sits on a main road leading to the cities of Sloviansk and Kramatorsk. Both are situated in the Donetsk region.

Attacks

In the 24 hours to Sunday morning, Russian forces targeted more than 30 towns and villages across Ukraine, launching five missile and 23 air strikes and up to 60 rocket attacks, the General Staff of Ukraine’s Armed Forces said on Sunday.

In response, Ukraine’s air forces carried out 32 strikes, hitting 24 Russian targets.

Fighting is particularly intense in the eastern provinces of Donetsk and Luhansk, and the strategically important Kherson province in the south, three of the four provinces Putin proclaimed as part of Russia last month.

Shelling by Ukrainian forces damaged the administration building in the city of Donetsk, capital of the Donetsk region, its Russian-backed administration said on Sunday.

Kirill Stremousov, a Russian-installed official in the Kherson region, said on the Telegram messaging app on Sunday that Russian forces had quashed an offensive by Ukrainian troops in the area and that the situation there was “under control”.

Ukraine’s Southern Command said its forces’ positions had come under repeated attack on Saturday and a small “shooting battle” had taken place near the village of Tryfonivka in the Kherson region.

Russian forces also fired nearly 20 Russian-made Grad rockets on the right bank of the Dnipro River in the Kherson region, it said.

Russia’s defence ministry said on Saturday its forces had killed more than 50 Ukrainian soldiers and destroyed five tanks near the Kakhovka Reservoir on the Dnipro River.

Reuters was not able to independently verify the battlefield reports.

Although Ukrainian troops have recaptured thousands of square kilometres of land in recent offensives in the east and south, officials say progress is likely to slow once Kyiv’s forces meet more determined resistance.

Ukrainian forces and civilians are relying on Starlink internet service provided by Elon Musk’s SpaceX rocket company. Musk said on Friday he could no longer afford to fund the service but on Saturday said he would continue to do so.

Zelenskiy said almost 65,000 Russians had been killed so far since the February 24 invasion, a figure far higher than Moscow’s official September 21 estimate of 5,937 dead. In August the Pentagon said Russia has suffered between 70,000 and 80,000 casualties, either killed or wounded.

Zelenskiy’s chief of staff Andriy Yermak said on Telegram on Sunday that Ukraine would prevail in the war because of the continued military aid it is receiving from the West and the cumulative impact of Western sanctions on Russia’s economy.

“Ukraine’s offensive is strategic and the defeat of Russia is inevitable,” Yermak said.
