More than 30 freight train cars derailed in Kentucky early Thursday, including at least one car that was actively leaking a dangerous chemical, authorities said.
The derailment occurred around 7 a.m. local time in a rural area of Todd County. A half-mile shelter-in-place order was issued and later lifted at 11 a.m.
Aerial images show derailed freight cars against one another along the tracks in rural Kentucky, with several cars tipped onto their sides and debris scattered across nearby fields.
One car spilled molten sulfur, which is sulfur heated to a liquid state and commonly used in industrial applications, such as fertilizer production. Molten sulfur can cause severe thermal burns and release irritating gases such as sulfur dioxide or hydrogen sulfide if disturbed, according to the Environmental Protection Agency.
