The Myla explosion exposed an ammunition-storage risk Ukraine has not yet shown it has reduced

Why the secondary explosion matters

The presence of different munitions created a second hazard after the Russian weapon hit. The precise quantities, storage duration and authorised limits have not been disclosed, so it would be premature to call the site illegal or to claim that a specific rule was breached. The death toll and geographic spread of the damage nevertheless show that the consequences were not confined to the original point of impact.

The UN’s International Ammunition Technical Guidelines call for storage quantities and distances to be set so that an explosion does not expose surrounding populations to unacceptable danger. Where prescribed distances cannot be maintained, authorities should reduce risk as far as reasonably practicable and formally accept any remaining danger. The guidelines also require licensing based on quantity and hazard, with civilian exposure considered when a site is approved. They provide an international safety benchmark, not proof of what Ukrainian law required at Myla.

Those guidelines do not answer whether Myla complied with its licence because Ukraine has released no licence, site limit or inspection record. They do identify the questions an investigation must resolve: how much ammunition was present, how close civilians were, who authorised the arrangement and whether previous inspections had recognised the danger.

An audit is recognition, not remediation

Following the Myla explosion, the second publicly acknowledged incident of this kind after Vyshneve in July, Ukraine’s Defence Ministry said all those responsible for weapons storage should complete a full audit of their locations. Zelenskyy said criminal proceedings were under way and expected details to be presented publicly and promptly. This response is more credible than concealing the storage failure, especially during wartime, but an audit instruction records an intention to inspect. Criminal proceedings may establish whether particular officials bear responsibility. Neither step, by itself, shows that ammunition at another exposed location has been moved, divided into smaller quantities or stored farther from civilians.

The government does not need to publish coordinates, inventories or operational vulnerabilities to demonstrate progress. It could release the audit’s deadline and responsible authority, confirm that temporary and dispersed stores are included, and report in aggregate how many sites exceeded approved quantities or presented unacceptable proximity to homes and evacuation routes. It could also state how many stocks were relocated or divided and how often exceptional risks received formal senior-level approval.

“The public test is whether the audit leads to ammunition being moved away from homes or divided into smaller quantities at exposed sites.”

The available evidence therefore answers the research question only in part. Russia’s strike initiated the Myla disaster, while Ukraine’s placement of ammunition near civilians increased the scale of the secondary explosion. Kyiv’s admission, investigation and audit instruction show that the government has recognised the problem. No published result yet shows that the same risk has been reduced elsewhere. That judgment should change when authorities provide non-sensitive audit findings showing that exposed stores were identified and stocks were moved, divided or formally reassessed under clear safety limits.
