An Italian bishop at the funeral for victims of a head-on crash between commuter trains is decrying what he calls the neglect of Italy's south.

Andria Bishop Luigi Mansi led mourners Saturday in a sports stadium, where the coffins of 13 of the 23 killed in the crash were laid side-by-side. Separate funerals are planned for the other victims.

Two trains collided Tuesday on a single track in an olive grove in Puglia, southeastern Italy.

Mansi said the south for too long has been considered "Italy's periphery" and cited a "lack of scruples" behind policies to save money at the expense of lives.

Human error is blamed for putting the trains on a collision course, but investigators also want to know why a second track wasn't built despite available funds.
