Police say he drove into a crowd at the event, then left the vehicle and stabbed several people, killing one woman and injuring 29 others.Chancellor Friedrich Merz vowed on Monday to take action in response to the fatal vehicle ramming attack on the Berlin Pride celebration over the weekend, with questions being asked as to why the suspected driver ​hadn't been in prison. Merz said that it is still ​too early to ​answer the question of what political ​consequences will be ⁠drawn ⁠from ‌the incident. "What is ‌also clear, however, is that we cannot stop ​at mere statements. ⁠We will have ⁠to respond ⁠with ⁠prudence, ​but also with determination," he said.The suspect, who was shot ​dead by police on Sunday, was identified as 21-year-old German citizen Abdul Ballout, who was recently convicted of preparing a violent act and was believed to ​have tried to join the Islamic State militant group.

Poland's foreign minister identified the individual as ⁠a Polish woman aged about 60. The Bild newspaper said the victim was visiting the Christopher Street Day celebrations with her daughter, who herself suffered injuries. Ballout was a German citizen with Lebanese roots ‌and born and raised in Berlin, according to Germany's interior minister.Police said they opened fire on him on Sunday when he ran toward officers armed with a bladed weapon.ISIS allegationsIn May, Ballout was convicted of preparing a serious act of violence endangering the state and was sentenced under juvenile law to one year and 10 months in prison, according to prosecutors. He was released under the supervision of a probation officer for six months after the court deferred a decision on whether to suspend the sentence.According to prosecutors, the case centred on allegations that Ballout sought to join Islamic State in 2025.German Chancellor Friedrich Merz speaks to the media in Berlin on Monday, while meeting with officials from the German Christian Democratic Union Party.

Meanwhile, the German federal prosecutors' office said on Monday that a second suspect who had been detained has since been released.
