Two workers were killed at the site due to the explosion, while two others were injured.
The victims have been identified as district residents Fayaz Ahmad Bhat of Pahloo, and Gulzar Ahmad Khan of Uttersoo Maidphall, according to police.
“We are on spot but so far we haven’t got any clues how the blast happened. The investigation will take some time,” Showkat Ahmad, an official at the camp told local media after he confirmed the incident.
The two who sustained injuries have been taken to the district hospital in Anantnag.
There have been a number of similar incidents in the past. In 2007, several people were killed in a fire which lasted for days, after an unintentional explosion at the ammunition depots.
