2- and 3-year-old found burned to death in car in Negev

Two siblings aged two and three years old were found burned to death mid-day on Friday, Negev District police reported. 
Negev police said they received the report of a burning car near the Dudaim forest in the northern Negev, and when police and rescue services arrived
they found the two children burned to death inside the vehicle. 
Police said they have ruled out the possibility that the fire was caused by a rocket and are checking either that the fire was caused by horseplay by the children or by arson. They added that they expect to bring people in for questioning in the coming hours.
