Two school buses have collided head on in northeast Washington and at least nine people are being transported to area hospitals, including several students.
A bus from D.C. schools and one from Prince George's County, Md., collided on Eastern Avenue near Booth Lane, D.C. Fire and EMS spokesman Pete Piringer said.
A man and a woman were seriously injured, Piringer said. They are thought to be the bus drivers.
Two other adults and five children also were taken to hospitals but are not seriously injured.
The children appear to be pre-teens. It wasn't immediately clear what schools they were from.
Eastern Avenue is closed in the area while an investigation continues, authorities said.
