Russia has been accused of not taking the bodies of dead soldiers home to hide the country's true death toll in Ukraine.
Iryna Vereshchuk, Deputy Prime Minister of Ukraine and Minister for Reintegration of Temporary Occupied Territories, said Russian leader Vladimir Putin is hiding the scale of the war from families during an all-Ukrainian telethon.
She said: "Obviously, believing that the bodies of servicemen of the Russian Federation are not worthy to return to their homeland and be buried humanely.
"At the same time, the Cabinet of Ministers of Ukraine has developed and approved a step-by-step procedure for their transfer.

"They leave their dead here in Ukraine without the right to be buried in the Russian Federation for one purpose: to prevent Russian mothers, wives and daughters from learning about the true scale of the war waged by Vladimir Putin, the thousands and thousands killed and the collapse that Russia is waiting if this war continues for some time to come.
"Such atrocities against even our people, of course, shock us. But they do not stop our army. We are on our land."
The Russian military is reportedly using mobile crematoriums to "incinerate dead soldiers" amid claims Putin is trying to hide the scale of his war.
Nine of Vladimir Putin's commanders have reportedly been killed, with Ukraine claiming a total of 12,000 Russian troops have died.
These figures have not been independently verified.
It comes as a Kremlin official reportedly described the invasion as a "clusterf***".
Farida Rustamova, a Russian journalist who maintained government sources after fleeing the country, said those she spoke to before leaving never believed Putin would go to war, MailOnline reports.
One source reportedly told her: "They're carefully enunciating the word clusterf***.
"No one is rejoicing. Many understand that this is a mistake, but in the course of doing their duty they come up with explanations in order to somehow come to terms with it."
Yesterday, it was reported two high-ranking Russian commanders were killed in the battle.
Lieutenant General Serhiy Shaptala said on Facebook : "In the course of hostilities, the city of Chuhuiv was liberated.
"Lieutenant Colonel Dmitry Safronov, Commander of the 61st Separate Marine Brigade of the Russian Armed Forces, and Lieutenant Colonel Denis Glebov, Deputy Commander of the 11th Separate Airborne Assault Brigade of the Russian Armed Forces, were killed."
The UN has recorded 406 deaths and 801 injuries among Ukraine’s civilian population since Russia's invasion began.
It comes as Putin said the "whole country" is proud of the Russian invading forces in a propaganda video released by the Kremlin.
This is despite thousands of arrests of anti-war protesters across the country and a crackdown on the independent press in the country.
In his speech, translated to English, Putin addresses the "mothers, wives and sisters, brides and girlfriends" of the Russian soldiers fighting in Ukraine.
"You can be proud of them," he said.
At least 100 people have been arrested at anti-war protests in Russia so far today, according to the OVD-info monitoring group.
A total of more than 4,300 people have reportedly been arrested so far as protests took place in 21 cities across Russia.
According to independent monitoring group OVD-Info, there have been 4,366 documented arrests since Russia's invasion of Ukraine 13 days ago.
A spokesperson for the group said: “The screws are being fully tightened – essentially we are witnessing military censorship.
“We are seeing rather big protests today, even in Siberian cities where we only rarely saw such numbers of arrests.”
