McEWEN, Tenn. (AP) — A catastrophic explosion at an explosives plant in Tennessee has left 18 people missing and feared dead, as search efforts continue amidst poignant anxiety from families waiting for news.

The blast occurred Friday morning at Accurate Energetic Systems, a facility dedicated to providing explosives for military purposes, ejecting debris over a half-mile area and felt by residents as far as 15 miles away.

Humphreys County Sheriff Chris Davis characterized the aftermath as 'one of the worst scenes' he has ever encountered, noting that while multiple fatalities are evident, the exact number is still unconfirmed as officials are still in contact with families of the missing. Davis referred to these individuals as 'souls' during a press briefing.

Aerial images reveal a scene of devastation; twisted metal, charred vehicles, and the remains of buildings emanating plumes of smoke are visible from above.

Known as a significant military contractor, Accurate Energetic Systems operates an expansive facility situated in wooded hills about 60 miles southwest of Nashville. The details about the workforce present during the explosion remain unclear.

Residents in the nearby community of Lobelville reported feeling the seismic impact of the explosion. Individual accounts describe intense fear as homes shook and some recorded the blast on surveillance cameras.

In response to this tragic incident, Tennessee Governor Bill Lee expressed his willingness to assist and support the affected families through a social media post. In a heartwarming gesture, a vigil was held on Friday night in honor of the missing and their families.

This incident is reminiscent of a long history of industrial accidents in the U.S., leading to critical safety regulations due to previous workplace disasters. Accurate Energetic Systems, noted for dealing with various types of munitions, including hazardous materials, has faced scrutiny for safety violations in the past.

As the community begins to heal from this heart-wrenching event, officials are launching further investigations to understand the cause of the explosion.
