Ukraine’s Foreign Minister Dmytro Kuleba described the situation in the besieged port city of Mariupol as a “red line” for the peace negotiations with the Russians, adding that there has been no recent diplomatic communication between Kyiv and Moscow at the foreign ministry levels.

“After Bucha, it was- it became particularly difficult to continue talking with the Russians. But as my president mentioned, Mariupol may be a red line”, - Kuleba told CBS News in an interview on Sunday.

“The situation in Mariupol is both dire militarily and heartbreaking. The city doesn’t exist anymore. The remainings of the Ukrainian army and large group of civilians are basically encircled by the Russian forces. They continue their struggle, but it seems from the way the Russian army behaves in Mariupol, they decided to raze the city to the ground at any cost”, - he added.
