European leaders are condemning the fatal stabbing of the mayor of the Polish city of Gdansk as a "shameless act" and a "senseless act of violence".
German President Frank-Walter Steinmeier wrote to Pawel Adamowicz's widow and said he was "particularly shocked that your husband was attacked during the closing rally of a donation campaign to raise funds for hospitals".
The mayor died this morning, less than a day after he was stabbed on stage at the fundraiser.
Czech Foreign Minister Tomas Petricek called Adamowicz's slaying "a great tragedy not only for Gdansk and Poland but for the whole of Europe and its citizens."
Petricek wrote on Twitter: "It is important to make clear that, irrespective of differences in political attitudes, we all strongly condemn this shameful act."
