At least 3 elephants were trapped in Mahanadi river, when floodgates of Mundali barrage, near Cuttack in Odisha were opened to release flood waters early this morning. The elephants were crossing the river, at the time when the floodgates opened. Two out of five tuskers managed to come out of the river. The gates of another barrage, Naraj had to be opened to rescue the remaining three elephants that were trapped. They walked back to safety once the water levels came down.
