TEHRAN (Press Shia) – Paweł Adamowicz, the mayor of Gdańsk in northern Poland, was stabbed on stage in front of thousands on Sunday evening in an apparent assassination attempt.

– World news –

Adamowicz, who has served as mayor of Gdańsk since 1998, was resuscitated at the scene and rushed to a nearby hospital where he underwent five hours of surgery. Doctors described his condition as “critical” and “serious”.

One of the surgeons, Dr Tomasz Stefaniak, said Adamowicz suffered a “serious wound to the heart, a wound to the diaphragm and to the internal organs” and had needed a huge amount of blood. Gdansk is holding a blood collection for Adamowicz on Monday and a rally against violence is also planned, the Guardian reported.

Adamowicz is a powerful liberal voice in a country that has been governed by the rightwing Law and Justice party since 2015. He is best known in Poland and internationally as a staunch supporter of migrant rights during a period of rising anti-migrant sentiment.

Polish media reports quoting police sources have named the alleged assailant as Stefan W, a 27-year-old from Gdańsk with a record of violent crime. Polish law restricts the surnames of people accused of a crime being reported.

It is understood that Stefan W was convicted of a series of violent assaults and sentenced to prison in 2014.

Video footage of the incident shows the assailant addressing the crowd from a microphone on the stage. He is reported as saying: “Hello! Hello! My name is Stefan. I sat innocent in prison, I sat innocent in prison. Civic Platform tortured me, and that’s why Adamowicz is dead.”
