Police in the southern U.S. city of Chattanooga, Tennessee arrested a school bus driver after a crash Monday that killed at least six children.
Authorities said the bus was carrying 35 students from an elementary school when it turned on its side and wrapped around a tree.
The driver has been charged with vehicular homicide, reckless endangerment and reckless driving.
Chattanooga Police Chief Fred Fletcher said there were no other vehicles involved in the crash, and that investigators were looking at speed "very, very strongly" as a factor.
"Our hearts go out, as well as the hearts of all these people behind me, to the families, the neighborhood, the school, for all the people involved in this, we assure you we are doing everything we can,'' Fletcher said at a news conference.
Twenty-three children were brought to hospitals, officials said. Hamilton County District Attorney Neal Pinkston told media outlets that five children died at the scene and one died at a hospital.
