TEL AVIV, Israel, Dec. 28 (UPI) -- At least 116 people were injured in a fire aboard a train traveling from Nahariya to Tel Aviv Tuesday, Israeli railway authorities said.
Five people sustained moderate injuries, Magen David Adom emergency services said. They were taken to hospitals in the region, suffering mainly from smoke inhalation and shock.
Yitzhak Harel, director of the Israel Railways Authority, told Maariv it was unclear what caused the fire despite media reports claiming an electric short in the rear engine.
Harel noted a warning system designed to open the train's doors automatically failed and one of the security guards opened them manually, he said.
Police commander Amihai Eshed told the Tel Aviv newspaper it appears a technical failure in the engine's control system caused the fire, the newspaper said.
Passengers debarked themselves. Some said they heard an explosion, Ynetnews.com said.
"Suddenly we heard a loud explosion and there was a sharp smell throughout the train -- the doors opened and we all fled in panic," a passenger told the Web site.
Police and rescue teams reached the site shortly after the fire was reported, Maariv said.
Israeli Transport Minister Yisrael Katz ordered an inquiry into the cause of the fire, which is also being investigated by police, the newspaper said.
