High winds have swept through northern Germany, knocking down trees that killed at least two people and causing widespread flight and train delays and cancellations.

Authorities in Hamburg warned residents Thursday to stay inside after a tree fell on a car and killed a woman, police told the dpa news agency. A truck driver was also killed near Rostock when a tree hit his vehicle.

In Berlin, where winds reached up to 120 kph (75 mph), flights were temporarily grounded at the city's two airports and much of the public transportation system was shut down.

Regional trains were also closed down in several northern states because of the danger from branches over the tracks.
