Russian forces attacked the city of Myrnohrad in eastern Ukraine, with two glide bombs overnight, injuring at least five people, the Donetsk Oblast Prosecutor's Office said.

The prosecutor's office said that the two bombs hit a residential part of the city, wounding four men between the ages of 22 and 43 and one 40-year-old woman. The injured people received medical attention, the prosecutor's office said.

Myrnohrad, which is located around 40 miles from the Russian-occupied regional capital of Donetsk, is regularly targeted in Russian attacks.

South Korean defence minister Shin Won-sik has said that more evidence suggests weapons used by Russia in the war in Ukraine were illegally imported from North Korea.

"Military cooperation between Russia and North Korea" is escalating tensions on the Korean Peninsula and "also affecting the battlefield in Europe", Mr Shin said.

If North Korea continues to receive military technology transfers from Russia in return, a significant improvement in North Korea's conventional military capability is an imminent risk, Mr Shin said.

Mr Shin was speaking during the Shangri-La Dialogue, Asia's biggest defence forum, under way in Singapore.

Twelve people, including a number of children, have been taken to hospital after a strike close to two houses where they were sheltering in the Kharkiv region, said the area’s Governor Oleh Syniehubov.

Russia has stepped up its attacks around Kharkiv in recent weeks.

The UK’s Ministry of Defence, however, has estimated that the number of Russian troops killed or wounded since the war’s outbreak ‘“has now likely reached 500,000”.

In May of this year, it adds, “average personnel casualties were over 1,2200 per day”.

Ukrainian President Volodomyr Zelensky has arrived in Singapore for the Shangri-La Dialogue, where he plans to meet the US defense secretary, Lloyd Austin, and discuss support for his embattled country in an address to delegates.

The International Institute of Strategic Studies (IISS), which organises the security conference, said he would participate in a discussion session on Sunday entitled "Re-Imagining Solutions for Global Peace and Regional Stability".

He is expected to ask attendees at the conference to attend and support a "peace summit" this month in Switzerland. Mr Zelensky said on Wednesday that Russia is trying to disrupt the summit, scheduled for June 15-16, which he hopes will generate support for the withdrawal of Russian troops and the restoration of Ukraine's 1991 borders.

Ukraine’s President Volodymyr Zelensky has hit out at the latest Russian strikes, while making a plea for more Western weapons: "Russia's main goal is to normalize terror, to use the lack of sufficient air defence and determination of Ukraine's partners," Mr Zelensky said on the Telegram messaging app.

"Partners know exactly what is needed. Additional "Patriots" and other modern air defence systems for Ukraine. To accelerate and expand F-16 deliveries to Ukraine. To provide our soldiers with all the necessary capabilities."

The US defense secretary, Lloyd Austin, has tried to refocus attention on China's threat in the Asia-Pacific, seeking to alleviate concerns that conflicts in Ukraine and Gaza have distracted from America's security commitments in the region.

Mr Austin, who was speaking at the annual Shangri-La Dialogue security summit in Singapore, met his Chinese counterpart, Dong Jun, on Friday in a bid to cool friction over issues from Taiwan to China's military activity in the South China Sea.

There has been increasing concern that Washington's focus on helping Ukraine counter Russia's invasion and support for Israel's war in Gaza, while trying to ensure that the conflict does not spread, has taken away attention from the Indo-Pacific.

"Despite these historic clashes in Europe and the Middle East, the Indo-Pacific has remained our priority theatre of operations," Mr Austin said in his speech, which appeared aimed at underlining the administration's legacy in the region as President Joe Biden's first term in office nears its end.

Mr Biden is running for re-election in November against former President Donald Trump.

"Let me be clear: The United States can be secure only if Asia is secure," Austin said. "That’s why the United States has long maintained our presence in this region."

Ukrainian air defence shot down 35 of 53 Russian missiles and 46 of 47 Russian drones during the latest attacks across the country, the air force commander has said. As air raid alerts were issued across Ukraine, Poland said its own and other allies’ warplanes were scrambled due to “intense long-range aviation activity of the Russian Federation tonight, related to air and missile strikes on objects located in the territory of Ukraine. All necessary procedures to ensure the safety of Polish airspace have been launched.”

Russia has launched a barrage of missiles and drones on Saturday, damaging energy facilities in five regions across Ukraine, officials said.

Ukraine's national grid operator Ukrenergo said the attack damaged energy facilities in the eastern Donetsk, southeastern Zaporizhzhia, and Dnipropetrovsk regions, central Kyrovohrad region, and Ivano-Frankivsk region in the west.

"The Russians launched another strike on Ukrainian energy facilities. Since March it is already the sixth massive, complex, missile and drone attack against the civilian energy infrastructure," Ukrenergo said.

Since March, Russia has stepped up its bombardments of the Ukrainian power infrastructure, knocking out the bulk of the thermal and hydropower generation, causing blackouts, and pushing electricity imports to record highs.
