Tour bus collides with 18-wheeler

A charter bus taking Italian tourists to Niagara Falls collided with a tractortrailer Wednesday on an eastern Pennsylvania highway, killing the bus driver and two others on the bus and leaving four people in critical condition, authorities said. The crash occurred shortly after 10 a.m. on Interstate 380 in the Pocono Mountain region as the bus, which departed from the New York metro area, was about a quarter of the way to its destination. All three of those killed were on the bus.
