Military unit claims to confirm report by Wagner boss that Russian brigade has been routed

A Ukrainian military unit has said it has routed a Russian infantry brigade from frontline territory near Bakhmut, claiming to corroborate an account by the head of Russia’s Wagner group that the Russian forces had fled.

Later on Wednesday, Col Gen Oleksandr Syrskyi, who heads Ukraine’s ground forces, said Russian units in some parts of Bakhmut had retreated by up to 2km (1.2 miles) as the result of counterattacks. He did not give details.

Suspilne, Ukraine's state broadcaster, offers this round-up of the latest developments overnight. It writes on its official Telegram channel:

In Bakhmut, fighters of the 3rd brigade of the armed forces of Ukraine advanced 2.6km during the storming of Russian positions for two days and defeated two companies of the 72nd brigade of the Russian Federation, said the commander of the “Azov” regiment.

Air defence forces destroyed three Russian drones over Dnipropetrovsk region on the night of 10 May. Also at night, the Russian army shelled Kherson heavily. More than 350 projectiles were fired in Kherson oblast during the day: one person was injured.

The transformation of our alliance over the last decade has been nothing short of remarkable. Since Russia illegally annexed Crimea and entered into eastern Ukraine in 2014, we have increased the readiness of our forces.

We have deployed combat troops to the east of the alliance for the first time in our history, and European allies and Canada have spent an additional $350bn extra on defence.

As we prepare for a more dangerous future, we must redouble our efforts to keep our one billion citizens safe, and to uphold the rules-based international order.

High intensity warfare is back in Europe, global competition is rising, authoritarian regimes are challenging our values, interests and security, and other threats are also multiplying – from terrorism to cyber-attacks, from nuclear proliferation to climate change. So we need to step up for this new era of strategic competition.

Ukrainian official says Russians in Bakhmut have been pushed back by up to 2km; Russia’s Transneft reports attack on oil pipeline

A Ukrainian military commander said Russian forces in Bakhmut had been pushed back by up to 2km in some areas after counteroffensives. Col Gen Oleksandr Syrskyi, who heads Ukraine’s ground forces, posted on Telegram: “In some areas of the front, the enemy could not resist the onslaught of the Ukrainian defenders and retreated.”

Russia’s oil pipeline operator Transneft said a filling point on the Europe-bound Druzhba pipeline had been targeted in a “terrorist attack” near the border with Ukraine, according to the Tass news agency. Transneft said nobody was injured in the incident.

Ukraine’s military said its forces had seriously damaged Russia’s 72nd independent motorised rifle brigade near Bakhmut, made up of thousands of troops. Serhiy Cherevatyi, a spokesperson for Ukrainian troops in the east, said the situation remained “difficult” in Bakhmut, but Moscow was increasingly having to use regular army units because of heavy losses among Wagner group fighters.

The Wagner boss, Yevgeny Prigozhin, complained that his fighters were still not getting enough shells from the defence ministry. In an audio statement, he said the defence ministry – which has promised to ensure that all combat units have the resources they need – had been holding long meetings on the shell issue, but there had been no breakthrough. “We’re not receiving enough shells, we’re only getting 10%,” Prigozhin said, according to Reuters.

The French parliament called on the EU to formally label the Wagner group as terrorists, as the UK reportedly prepares to do the same. France’s parliament unanimously passed a non-binding resolution aimed at encouraging the 27 members of the EU to put Wagner on its official list of terrorist organisations.

Russian forces plan to evacuate more than 3,000 workers from the town that serves the occupied Zaporizhzhia nuclear power plant, where there is a “catastrophic lack” of qualified personnel, Ukraine’s state-owned Energoatom company said. Ukraine has repeatedly accused Russia of forcibly deporting its citizens from occupied Ukrainian regions to Russian Federation territory.

Germany’s former chancellor Gerhard Schröder has been criticised again for his links to Russia after attending a Victory Day party at the Russian embassy in Berlin. Schröder was seen at a reception on Tuesday marking the anniversary of the defeat of Nazi Germany in the second world war, along with senior figures from the far-right Alternative für Deutschland party and the far-left Linke party.

Russia may formally denounce the treaty on conventional armed forces in Europe, which it pulled out of in 2015, according to a decree signed by Vladimir Putin on Wednesday. The decree formally appoints the deputy foreign minister Sergei Ryabkov to represent Putin during parliamentary proceedings on denouncing the treaty, which aimed to regulate the number of forces deployed by Warsaw Pact and Nato countries.

The North Korean leader, Kim Jong-un, said Russia “will prevail” in its fight against what he described as “imperialists”, the state news agency KCNA said on Tuesday, in remarks seen to be aimed at Ukraine and its western supporters such as the US.

North Korea has forged closer ties with the Kremlin and backed Moscow after it invaded Ukraine last year, including its proclamation later of having annexed parts of Ukraine, which most UN members condemned as illegal.
