Lightning strikes have turned into one of the deadliest natural disasters in Bangladesh, claiming over 200 lives every year.
At least 216 people die every year on an average in lightning strikes, more than by floods, cyclones and other calamities.
More than 70 per cent of the total lightning strikes occur between April and June, say experts.
