According to official data, as many as 79 houses, 52 shops, 2 schools, 3 factories and 4 mosques were burned.
A senior fire official noted that 25 calls reported vehicles in flames, and over 500 cars, trucks and busses were gutted.
An estimated 218 calls reporting fire incidents were reported in riot-hit northeast Delhi between Monday and Thursday.
According to a senior fire official, fire-fighters were challenged to reach affected locations, in many cases only made possible through the support of police officials.
"As many as 1,000 trips were made in the entire northeast district area by our fire vehicles. During the violence, five fire engines were damaged, including one which was completely charred. Some of the firefighters even had to take shelter to save themselves after the vehicles were attacked," a senior fire official said.
