Gas leak kills 11 in India's northern Punjab state

A gas leak killed 11 people in India on April 30, an official said, in the latest deadly industrial accident in the vast developing economy of 1.4 billion people.

The gas leak happened in Giaspura, an industrial area of Ludhiana in the northern state of Punjab, The New Arab reports.

"Eleven deaths are confirmed," Mandeep Singh Sidhu, police commissioner of Ludhiana, told reporters, adding that four people were hospitalised.

The cause of the leak was yet to be ascertained, Sidhu added.

"When the blood sample is matched with the sample that the NDRF (National Disaster Response Force) team takes, only then will we be able to tell you the exact cause, which kind of gas," the police commissioner said.

Five women were among those who died, broadcaster NDTV reported.

The six other victims included two boys aged 10 and 13, the report added.

Industrial gas leaks blamed on poor safety standards and insufficient checks are common in India.

Last August, at least 112 women were hospitalised after a gas leak at an apparel manufacturing plant in the southern state of Andhra Pradesh.

That followed a similar accident in June when around 200 women fell unconscious after a gas leak in the same area, NDTV reported.
