German Chancellor Friedrich Merz said the latest peace plan draft for Ukraine has been presented to US President Donald Trump - including a proposal on territorial concessions Kyiv may be prepared to make.

But Merz highlighted the territorial issue was "a question that must be answered primarily by the Ukrainian president, and the Ukrainian people."

"We also made this clear to President Trump," Merz pointed out.

In recent weeks European leaders have worked closely with Ukraine to come up with a new iteration of a peace plan that addresses Kyiv's interests and concerns.

Trump appears to have grown frustrated with the intricacies of the question of sovereignty over Russian-occupied Ukrainian territories.
