Atleast three people were seriously injured in an accident on I-95 in New Hampshire this morning involving a bus from a Maine daycare.

The accident happened in the town of Greenland, New Hampshire and involved a bus from a daycare facility that's part of the Kittery Community Center. The Portsmouth Herald says one of the seriously injured was a child. They were taken to Portsmouth Hospital with injuries that are not believed to be life-threatening. Several other kids on the bus were taken to Exeter Hospital for evaluation but the extent of their injuries isn't known, at this time.

Officials say the bus was the only vehicle involved and that the driver was trapped after the accident.
