Lightning strikes killed at least 120 people in four Indian states as monsoon rains swept across much of the country.

“Lightning strikes are common during monsoons, but there have been more strikes than usual this year,” said Vyas Ji, principal secretary in Bihar, where a record 57 people died Tuesday from the strikes – the most of any state in the country.

Lightning is the leading killer among natural disasters in India. In 2014, at least 2,582 people died in lightning strikes, according to the government.
