A left-leaning mayor in Poland was stabbed on Sunday night by an assailant with political grievances, officials said.
Pawel Adamowicz, the mayor of the northern coastal city of Gdansk, was stabbed in the heart while he spoke at a fund-raiser organized by the Great Orchestra of Christmas Charity, The Associated Press reported.

The assailant shouted from the stage that he had been wrongly imprisoned under a previous national government led by Civic Platform, a centrist party, The A.P. said.
Mr. Adamowicz was once a member of Civic Platform, which is now Poland's biggest opposition party. The head of the Great Orchestra of Christmas Charity, Jerzy Owsiak, is a liberal critic of Law and Justice, the right-wing and populist party that in 2015 swept to power in Poland on the strength of the rural vote.

Mr. Adamowicz, 53, has been mayor of Gdansk since 1998 and was re-elected as an independent in November elections that underscored a deep divide between Poland's liberal cities and conservative countryside. He has advocated gay rights and tolerance for minorities, and expressed solidarity with the city's Jewish community last year when a synagogue's windows were broken.
The A.P. quoted the police as saying the suspect in the knife attack was a 27-year-old with apparent mental problems who had previously carried out bank robberies, and that he had gained access to the area where Mr. Adamowicz was speaking with a media badge.
Mr. Adamowicz was brought to the Medical University of Gdansk for surgery after the attack. The A.P. quoted Dr. Tomasz Stefaniak, a doctor at the hospital, as saying early on Monday morning that Mr. Adamowicz was alive but remained "in a very serious condition."
In a Twitter post on Sunday night, Sadiq Khan, the mayor of London, condemned the attack on Mr. Adamowicz and expressed solidarity "with the city he leads, his family and supporters."
