Ukranian news
are certainly coming fast and furious. Arthur starts with the good news:

The good news is that thanks to the mediation by the Polish president Aleksander Kwasniewski and the EU foreign policy head Javier Solana, both sides have sat down together and agreed to set up a working group to continue talks, and they also agreed to renounce violence in settling the dispute.

President Leonid Kuchma is not happy, and said: "As I understand, the (working group) talks are going on with considerable difficulty. No one can say what sort of compromise can be found or whether one will be found at all."
