The mayor of the northern Polish city of Gdansk is reported to be in a very serious condition after being stabbed while on stage at an event for the country's most important charity. A rally against violence is also planned.
Dr Tomasz Stefaniak, from the Medical University of Gdansk, said today that the mayor is "alive but is in a very serious condition".
Later Monday, the chief doctor for the Gdansk region, Jerzy Karpinski, said that Adamowicz is on life support and that "prognosis for his life and health is uncertain" after he lost a lot of blood that caused oxygen deprivation to his whole body.
Doctors operated for five hours on Mr Adamowicz, who was stabbed in the heart and abdomen on Sunday by an ex-convict who rushed onto the stage with a knife.
After knifing the 53-year-old major several times, the man turned to the crowd with his arms raised triumphantly but was quickly apprehended by security guards and arrested.
The official was taken to hospital, where he underwent emergency surgery.
Police said the suspect was a 27-year-old who had been recently released from prison, where he had served a term for bank robberies.
He shouted that he had been wrongfully imprisoned under the previous government of the party which had supported Mr Adamowicz's re-election.

Walker and Mfiondu Kabengele comprise a talented core that, on their home floor, could potentially push this Duke team a bit. Florida State could slip a little but is also deserving of holding on to its top-15 ranking.
Logan Paul Under Fire for Saying He'll 'Go Gay' for a Month
Ultimately, the notion that Paul and "Big Mike " could "Go Gay" just for the hell of it, invariably fell into the wrong hands. Meanwhile, filmmaker Hazel Hayes added: 'Call me when Logan Paul chooses to be a decent human being for a month'.
He said Mr Adamowicz needed massive blood transfusions.
One witness told broadcaster TVN the man appeared "happy with what he had done". He blamed what he described as an atmosphere of hate under the ruling Law and Justice party for the attack on the mayor.
Since winning office in 2015, the PiS has systematically blamed PO politicians for an array of issues, ranging from Value-Added Tax fraud to the 2010 crash of a Polish presidential jet in Russian Federation that claimed the life of then president Lech Kaczynski, the identical twin brother of PiS leader Jaroslaw Kaczynski.
Polish mayor Pawel Adamowicz has died in hospital after being stabbed on stage at a charity event.
"I phoned my boss to let him know, he understood", another donor told the newspaper.
Also on Twitter, President Andrzej Duda said: "I pray for his return to health and full strength". More than five hours after the attack there were no updates on his condition.
Polish police confirmed last night they had detained a suspect following the incident.
Nearly seven hours after the assault, Stefaniak told reporters early Monday that "the patient is alive", triggering applause, but added that the mayor remained "in a very serious condition".
