MEXICO CITY, August 24 (RIA Novosti) - At least 10 people were injured in a gas explosion in the center of Brazil's largest city of Sao Paulo on Saturday, local Telesur channel reported.
Three people are in critical condition.
The accident was caused by a gas leak from an underground pipeline. The explosion in the city's Chinatown area took place while maintenance workers were testing the pipe after a call about a possible leak due to heavy gas smell.
In May, a similar gas explosion in a fitness center on Sao Paulo's outskirts claimed two lives, and nine people got injuries of varying severity. A large part of the building, which contained water heaters for the swimming pool, collapsed during the explosion.
