Two young children have died in a mobile home fire in western Indiana, authorities say.

Three-year-old Athena Holdbrook and 3-month-old Aries Romine died in the fire Wednesday night at Northview Country Estates outside Brazil, Clay County Coroner Nick French said.

Both children died from smoke inhalation, French said. They were pronounced dead at the scene.

"Tried to go into the front door, but the heat was so overwhelming, and the smoke was so overwhelming. It was like I was being pushed back out. I tried to go back in twice, but I couldn’t get in. I couldn’t do anything but fall on my knees and pray," Muhammad said.

"It was horrifying to watch," neighbor Leeann Chandler added, "knowing they were still in there and there was nothing we could do."
