With peace talks between Russia and Ukraine set to take place in Turkey this week, Ukrainian President Volodymyr Zelenskyy insisted on the territorial integrity of his country after earlier suggesting he was ready for a compromise.

Zelenskyy said in his video address to the Ukrainian people late on Sunday that in talks due to take place in Istanbul his government would prioritize the "territorial integrity" of Ukraine.

But in comments made to Russian journalists earlier in the day, Zelenskyy adopted a different tone, saying Ukraine was willing to assume neutral status and compromise over the status of the eastern Donbas region as part of a peace deal.
