Ukraine claims that five “powerful” missile strikes hit the western city of Lviv, killing six people.

The situation in Mariupol, according to Ukraine’s foreign minister, is serious and painful, and Russia’s continuous attacks there might represent a “red line” that puts an end to all efforts to seek a peaceful resolution through discussion.

Russian forces have effectively ringed the remaining Ukrainian military personnel and citizens in the port city, according to Dmytro Kuleba of CBS’ “Face the Nation.”

The Ukrainians “continue their resistance,” he says, but the city “essentially no longer exists” due to tremendous destruction.

In recent weeks, Kuleba claims, his country has maintained “professional level” conversations with Russia in the hopes of establishing a political settlement for peace. However, he echoed Ukrainian President Volodymyr Zelenskyy in suggesting that the expulsion of Ukrainian forces in Mariupol might be a “red line” that halts peace talks.
