Russia forcibly took thousands of people in the besieged city of Mariupol and deported them to remote Russian cities, according to the Ukrainians.

Mariupol, a strategic coastal city that has been the target of intense attack from Russia, was being taken against their will across the border and farther into Russia, according to Inna Sovsun, a Ukrainian MP.

They are taking Ukrainian citizens, sending them through what are called filtration camps, and then relocating them to distant parts of Russia to work for free.

According to the reports, people were being sent by rail to various economically depressed cities in Russia.

Denisova said in a Telegram post that citizens have been issued papers that require them to be in a certain city for at least two years. The fate of others is unknown.

The Mayor of Mariupol likened the developments to the events of World War II when the Nazis forcibly captured people.

During World War II, Nazi Germany deported Jews and other groups to ghettos, shooting sites, and concentration camps. According to the Holocaust Memorial Museum, in many of the camps, Nazis exploited the forced labor of their enemies for economic gain and to meet labor shortages during the war.

"It is unconscionable for Russia to force Ukrainian citizens into Russia"

The reports of forced removal have not yet been verified.

The US ambassador to the United Nations, Linda Thomas-Greenfield, told CNN on Sunday that the tactic would be unconscionable.

I have only heard it. Thomas-Greenfield told CNN that it was disturbing. It is not right for Russia to force Ukrainian citizens into Russia and put them in concentration and prisoner camps.

According to the state news agency, the Defense Ministry of Russia claimed over the weekend that more than two million Ukrainians had asked to be evacuated to Russia.

Hundreds of Mariupol residents arrived in different cities across Russia according to a report by RIA Novosti.

480 people got to Yaroslavl, 400 miles from Ukraine, to be housed at a sanatorium, according to RIA. One evacuee said it was his dream to live in Russia.

Over 300,000 people are believed to be trapped in Mariupol, enduring weeks of Russian bombardment with no power or running water.

Mariupol's defenders were given a Russian deadline to lay down their arms in exchange for safe passage out of the city.
