https://www.politico.eu/article/german-far-right-mp-hospital-politically-motivated-attack-frank-magnitz/There is a rather graphic picture in Salvini's tweet in this article, so I'll just warn you lol.
Police in Bremen say they strongly suspect the attack was politically motivated considering the function of the victim. This comes a few days after an explosion outside a local AfD office in Germany. Today police also arrested a 20-year old man who allegedly stole data of celebrities and public officials (politicians of all political parties except the AfD where targeted). Last year a pro-refugee politician (Andreas Hollstein, CDU) was stabbed. This obviously isn't Weimar Germany 2.0, but the rise in political violence and vandalism in Germany is rather worrying to say to the least.
