The mayor of Kyiv, Vitali Klitschko, has told the BBC that Ukraine may have to give up land as part of a peace deal with Russia, amid a growing pressure from President Donald Trump to accept territorial concessions.

Russia pounded Kyiv with missiles and drones overnight, killing at least eight people, wounding more than 70 and smashing buildings in the biggest attack on the Ukrainian capital this year.The attack set off fires and six children were among the wounded,

Diplomatic initiatives are multiplying to end the conflict, but significant disagreements persist among Ukrainians, Russians, Americans and Europeans regarding the conditions for a lasting peace.

The president’s comments came after he said Crimea “will stay with Russia,” a position backed by the mayor of Kyiv, who conceded that his country may have to give up territory.
