The explosion was allegedly caused by a gas leak from a pipe that runs under the temple. According to preliminary data, the detonation occurred when someone tried to turn on the air conditioning.
Six air conditioners exploded at about 8:30 p.m. local time on Friday as they were preparing to recite their prayers. There were between 40 and 45 people in the mosque.
"We sent 37 injured people to the hospital. Most of the victims have burns on 60 to 70 percent of their bodies," local Fatullah city police chief Aslam Hossain said.
