On Tuesday, a military ammunition disposal site exploded near the Donguz rail station in Russia’s Orenburg region, making local residents leave their houses.

      A total of more than 4,000 tons of ammunition exploded, according to the Russia's Investigative Committee's reports, 2,000 280-mm rockets, 400 tons of aviation bombs and 1,379 tons of 100-mm shells among them.

      The spontaneous ammo explosion took place at 10:57 a.m. Moscow time, followed by a huge fire. Nearly 300 officers and soldiers had enough time to run to a safe distance, so no casualties were reported. However, four local residents were injured by fragment of broken glass.

      Donguz has been partially evacuated, and road traffic on the Sol-Lipetsk highway has been stopped. The fire was contained, its cause has yet to be established.

      The incident is the latest in a series of blasts involving munitions disposal sites and firing ranges in Russia in the last few years. Critics say the main reason is a gross security violation at the military ammunition disposal sites in Russia.
