Three people were dead and 20 injured in a shooting at a Catholic school in the south end of Minneapolis on Wednesday, a U.S. Justice Department official said.
The shooter was among those killed, said the official, who spoke on condition of anonymity.
The shooting occurred two days after school started at Annunciation Catholic school, a private elementary school with about 395 students. The school is connected to Annunciation Catholic Church, and both are located in a residential area in the southeast part of Minnesota's largest city.
Police in Richfield, a nearby suburb, said a man dressed all in black with a rifle was reported at the scene. A news conference was expected around 10:30 Central time, according to local TV.
