WARSAW, Poland (AP) — The mayor of a city in Poland was stabbed Sunday while he was on stage during the finale of a large charity event and he was transported to a hospital, officials and Polish media reported.

Gdansk Mayor Pawel Adamowicz was attacked with a sharp tool during the "Light to Heaven" charity event, charity spokeswoman Magdalena Skorupka-Kaczmarek, told Polish news agency PAP.

She said there was no immediate word about the mayor's condition at the hospital. Adamowicz has been mayor of Gdansk, a Baltic port city, since 1998.
