EAST PALESTINE, Ohio (AP) – Crews in Ohio began releasing toxic chemicals from five cars of a derailed train near the Pennsylvania state line on Monday afternoon to reduce the threat of an explosion. Flames and black smoke billowed high into the sky from the derailment site Monday afternoon. The Ohio Emergency Management Agency confirmed the controlled release was underway. Ohio Gov. Mike DeWine earlier ordered residents near the site to evacuate. DeWine said residents need to leave the area because of the risk of death or serious injury. Officials believe most, if not all of the people, ordered to leave had already left before officials issued the warning.
