Ukrainian President Volodymyr Zelensky says there "will be no lasting peace without territorial integrity" during a statement at the end of the first summit on peace in Ukraine, held in Switzerland. Zelensky further thanks "all the participants of the first peace summit for taking the first steps towards peace together. We are responding to Russia's full-scale invasion of Ukraine, not only with a full-scale defence of human life but also with full-scale diplomacy." SOUNDBITES
