The United States has ruled out reopening any new inquiry against Union Carbide after an Indian court's verdict in the 1984 Bhopal gas leak that killed over 15, 000 people, hoping it would bring closure to the probe into the tragedy.

"Obviously this was one of the greatest industrial tragedies and industrial accidents in human history," US Assistant Secretary of State for South Asia Robert Blake told reporters Monday. "We hope that this verdict today helps to bring some closure to the victims and their families."
