KIEV, April 18. /TASS/. Ukrainian politician Viktor Medvedchuk has called on Presidents Vladimir Putin of Russia and Vladimir Zelensky of Ukraine, to swap him for servicemen and Mariupol residents.

"I, Viktor Vladimirovich Medvedchuk, want to ask Russian President Vladimir Putin and Ukrainian President Vladimir Zelensky that the Ukrainian side exchange me for Mariupol defenders and residents, who are still there and cannot safely leave the city through humanitarian corridors," he said in a video address posted on the Telegram channel of the Ukrainian Security Service (SBU) on Monday.

According to the SBU press service, "around 120,000 civilians," as well as Azov battalion militants and marines from the 36th brigade are holed up in Mariupol.
