A car plowed through a park during Berlin’s biggest L.G.B.T.Q. Pride event, killing at least one person and injuring more than a dozen others, city police officials said on Saturday.

The police said that it happened shortly before 10 p.m. in the Tiergarten, a major park in the city center, and that a hunt for a suspect or suspects was underway. Florian Nath, a spokesman for Berlin’s police, said in an interview that at least 14 people had injuries, some of which were life-threatening. He added that a motive for the attack was under investigation.

Mr. Nath said the car “drove through the park and hit several people walking” in it. He said the park was near the Brandenburg Gate where a festival was underway in celebration of gay pride. It was not clear how the car entered the park.

The vehicle, Mr. Nath added, “didn’t exactly hit the parade,” but, by driving through the park, “attacked the people who were going away from the parade.”

The police said the car, a white, four-person passenger vehicle, was found crashed into a tree, with nobody inside.

The remainder of Christopher Street Day, a major Pride festival that is among the biggest in Europe, was canceled. The event, named for the New York City street known for its associations with the gay rights movement, draws hundreds of thousands of people to Berlin each year.

The police said on social media they were responding with emergency crews at the scene and urged people to avoid the area.

There have been several vehicle attacks in Germany in recent years in which assailants drove into crowds. The deadliest of these occurred in Magdeburg, in eastern Germany, in December 2024, when a driver plowed through a Christmas market, killing six people and injuring 309 others.
