President Volodymyr Zelenskyj may be forced to make a "painful decision" to achieve peace, says Klytjko to BBC.
One of the scenarios is to give up territory. It's not fair. But for peace, temporary peace, it may be a solution, temporarily.
However, he has not himself discussed details about a possible peace agreement with the president, he says. At the same time, Vitalij Klytjko emphasizes that the Ukrainian people will never accept a Russian occupation.
Ukraine is under great pressure from several directions. The USA has presented a peace proposal that involves "freezing" the conflict along the current front lines.
During the night towards Thursday, Russia carried out a large-scale attack on the capital Kyiv, where at least twelve people were killed and 90 injured, the deadliest Russian attack on the capital in several months.
