At least 16 people were injured in a fire incident that followed a gas cylinder blast at a four-storeyed building in Mumbai’s Lalbaug area on Sunday morning, officials said.

According to a fire personnel, four out of these sixteen people, including a minor, are in a critical condition as they sustained 70 to 95 per cent burn injuries.

The blaze erupted around 7.20 am on the second floor of Sarabhai building in Ganesh Galli locality, he said.

“There was a cylinder blast after gas leakage. The wall of a room collapsed after the blast,” Kishori Pednekar, the Mayor of Mumbai, told PTI.

“I personally visited the spot. The condition of a minor girl is stated to be critical and she is referred to Masina Hospital (at Byculla in south Mumbai),” she added.

The cylinder blast resulted in a fire in the building premises, which in turn injured 16, a fire official said.

He added that the injured persons were admitted to the KEM Hospital and Global Hospital in Parel area, as well as other medical facilities.

It was a 'level-one' (minor) fire. Two water tankers were rushed to the spot and the blaze was brought under control by around 7.50 am, he said.
