A fire and explosion tore through an Italian ammunition factory that supplies weapons for Ukraine’s war effort, but officials say no one was hurt.

Story Snapshot

A fire and blast hit the KNDS Ammo Italy plant in Colleferro, near Rome, on August 13, 2026.
No injuries or deaths were reported, according to local officials and the company.
The blast likely started in the powder-pressing area, where explosive powder gets compacted.
Italian prosecutors opened an investigation, including a possible arson angle.
The plant’s link to Ukraine’s ammunition supply has fueled online talk of sabotage, though no evidence backs that claim.

Fire Breaks Out At Munitions Plant Near Rome

A fire broke out at the KNDS Ammo Italy factory in Colleferro, a town about 40 miles southeast of Rome, on August 13, 2026. The fire came before a loud explosion that rattled the area. Emergency crews rushed to the scene as smoke rose over the industrial site.

Francesco Rocca, president of the Lazio region, said keeping people safe came first. “At this time, the absolute priority is to ensure people’s safety and allow all personnel involved in the emergency response to operate under the best possible conditions,” he said.

No Injuries Reported Despite The Blast’s Force

Reports from the scene say no one was hurt in the explosion. The Washington Post described a blast that “causes fright but no injuries,” and other outlets confirmed local officials found no reports of injured workers or bystanders. Workers on shift that day were moved to safety before or during the incident, according to multiple accounts of the response.

The number of workers on site that day is not fully clear. Some reports say about 22, others say 24, and a few simply describe “a handful” of employees present during the shift. That gap shows how fast-moving early reporting can vary even on basic facts like headcount.

Investigators Focus On Powder-Pressing Area

Multiple reports point to the plant’s powder-pressing or powder-compaction department as the likely starting point of the fire. This is the part of the factory where explosive powder gets pressed and shaped, a process known to carry fire risk in munitions plants worldwide. KNDS, the company that owns the factory, said it was too soon to confirm exactly how the fire started.

“The circumstances surrounding the incident are currently being investigated and assessed by the teams on site,” the company said, adding it was “too early to provide confirmed information on the cause or the sequence of events”. Prosecutors in nearby Velletri opened a file on the case, and reports say they are looking into a possible arson angle as one line of inquiry.

Plant’s Role In Ukraine Supply Chain Draws Attention

The factory, once known as Simmel Difesa before KNDS took over, makes ammunition tied to the war effort in Ukraine. That connection has drawn heavy attention online, with some social media posts suggesting Russian sabotage. No official statement from Italian authorities, KNDS, or prosecutors has presented evidence of a deliberate attack. The working theory so far remains an industrial accident under review.

Fires and explosions at munitions plants are not new. Facilities that handle explosive powder face recognized risks tied to compaction, mixing, and heating steps in production. Industry safety reviews of past incidents show that unsafe handling, storage problems, or process failures often play a role, though each case requires its own investigation before a cause gets confirmed.

For now, the confirmed facts are limited but clear: a fire and explosion hit a defense plant near Rome, no one was hurt, and Italian officials are still working to determine exactly what happened. Given the plant’s role supplying Ukraine, the incident lands at a sensitive moment for European defense production and will likely draw continued scrutiny as the investigation moves forward.
