The Russian army reportedly had a record 1.500 casualties per day in October

In October, an average of around 1.500 Russian soldiers were killed or wounded every day - the worst month for the Russian military since the start of the invasion, British Army Chief of Staff Tony Radakin said.

"Russia is close to reaching 700.000 people who have been killed or wounded - the enormous pain and suffering that the Russian people have to endure because of the ambitions of President Vladimir Putin," Radakin told the BBC on November 10.

Moscow does not publish the number of its war victims.

Radakin claims that Moscow spends more than 40 percent of public funds on defense and security, which puts "tremendous pressure" on the country.

Meanwhile, Russia's Defense Ministry claims its forces have captured the town of Volchenko in eastern Ukraine's Donetsk region, where Russian forces have made advances in recent weeks.
