West Bengal Chief Minister Mamata Banerjee on Tuesday said "negligence and callousness of some people" was responsible for the stampede at a railway foot-overbridge in Howrah that killed two and injured 12 others, urging the railways to take proper care of the passengers.

Referring to the horrific train accident in Punjab's Amritsar four days ago in which at least 59 people died and scores injured, Banerjee said the department should initiate inquiries into the matters rather than shying away from taking responsibility.
