Pallade Veneta - Deadly strikes hit Russian, Ukrainian border cities

Both sides also claimed to have advanced on the battlefield -- Moscow in eastern Ukraine and Kyiv in its shock offensive into Russia's western Kursk region -- with the fighting showing no sign of subsiding, two and a half years into Russia's invasion.

A Russian aerial strike on the northeastern city of Kharkiv on Friday afternoon killed seven people, including a 14-year-old girl, Ukraine's interior minister said.

Emergency workers were still pulling bodies from the rubble late on Friday evening. Images on social media showed the top floors of a multi-storey residential building ripped open and a fire raging after the strike.

At least 77 were wounded, including 18 children, the emergency services said.

President Volodymyr Zelensky called on Kyiv's Western backers to up their support after the attack, which officials said was with a glide bomb.

"We need strong decisions from our partners to stop this terror," Zelensky said in a post on social media.

"We need long-range capabilities," he added, referring to Kyiv's appeals to allies to lift restrictions on the use of Western-supplied missiles inside Russian territory and deliver more longer-range weapons.

"We need the implementation of air defence agreements for Ukraine. This is about saving lives," he added.

- Belgorod hit -

Across the border some 60 kilometres (37 miles) to the north, Russia said Ukraine had fired cluster munitions on the city of Belgorod and its suburbs, killing at least five and wounding 37 civilians, including at least six children.

"One woman and four men died of their wounds on the spot before an ambulance arrived," regional governor Vyacheslav Gladkov said in a post on Telegram.

He posted a video showing a fire raging at a house after one of the strikes. The state-run TASS media agency posted pictures of a road in the city of Belgorod covered in strewn debris and twisted metal.

Both Belgorod and Kharkiv have been hit repeatedly with aerial strikes throughout the war.

Russian President Vladimir Putin in May launched a new offensive into the Kharkiv region which he said was designed to push Ukrainian forces back to create a "security zone" for Russia's own border settlements.

Moscow's troops also claimed Friday to have captured three more villages in eastern Ukraine -- one in the Kharkiv region -- as they press against Ukrainian troops facing manpower and ammunition shortages.

Ukraine also claimed on Friday to have advanced in Russia's western Kursk region, where it is mounting its own surprise ground offensive, claiming to have captured 100 settlements and more than 1,200 square kilometres of territory since August 6.

- Commander fired -

Zelensky on Friday dismissed the country's air force chief, a day after Kyiv said a US-made F-16 fighter jet had crashed in combat, killing the pilot.

In a video message Zelensky said he had "decided to replace the commander of the air force" to strengthen Ukraine's military leadership.

His office earlier published a presidential decree to officially remove Mykola Oleshchuk from the post.

The crash of the F-16 was a high-profile setback for Kyiv, which had lobbied the West to send the advanced fighter jet for months.

The military had said the plane and pilot crashed during a combat mission earlier this week after having shot down incoming Russian missiles.

Zelensky did not provide further details on why he had decided to replace his air force commander, saying only that his command team "needed to get stronger".

Lieutenant General Anatolii Kryvonozhko, who leads the air force's operations in the central part of Ukraine, has temporarily assumed the role of overall commander.

Kyiv also on Friday issued a plea for Mongolia to arrest Putin when he visits the country next week.

It is the Russian leader's first trip to a country that is a member of the International Criminal Court (ICC) since The Hague-based body issued an arrest warrant for him last year over the alleged deportation of Ukrainian children to Russia.

Mongolia is technically obligated to detain him, though the Kremlin said Friday it was not concerned about that possibility and there is little the ICC can do if it chooses not to.
