At least 107 people have died from lightning strikes in northern and eastern India, officials said, during the early stages of the annual monsoon season.

Some 83 people were killed in the impoverished eastern state of Bihar after being struck by lightning, and another 24 died in northern Uttar Pradesh state. Dozens more were injured.

Lightning strikes during the June-September annual monsoon are fairly common in India. But Bihar’s disaster management minister, Lakshmeshwar Rai, said this was one of the highest daily tolls from lightning the state had recorded in recent years.
