In the last couple of days, there have been various diplomatic efforts to try and sort this out, discussions between Ukraine officials and Russian officials, but repeatedly when there have been some agreements made, particularly about safe passage and temporary ceasefires, the Russian side seem not to have got the message through to the people on the end of the guns, and that is a problem. When it comes to diplomacy, there is a need for basic respect, there is a need for an understanding and trust that whatever agreement is reached will be exercised by either of the parties. It's useful, I think, that the Israeli Prime Minister, Naftali Bennett, has had a face-to-face talk with Mr Putin. The world cannot be in a position of saying he was shut off and no one talked to him, and therefore we accept the consequence of this. There is a need to constantly state directly to that man that his regime undertaking this sort of action is unacceptable to the whole world.
