Lac-Megantic disaster: Engineer blamed for Canada blast

11 July 2013 Last updated at 07:21 BST

A train operator's boss has blamed a local engineer for a runaway train that derailed and exploded in a Quebec town, killing at least 20 people.

Rail World head Edward Burkhardt said he did not believe the last engineer had set a series of hand brakes, despite his protestations.

Residents heckled Mr Burkhardt as he visited the town of Lac-Megantic.

At least 30 other people are missing since Saturday morning's disaster and are "most probably dead", police say.

David Willis reports.
