NEW DELHI - Lightning killed at least 11 people in eastern India as large swaths of the country reeled under the worst floods in years that have left hundreds dead and millions displaced, officials said on Monday.

The victims were working in fields in Odisha state when lightning bolts struck them, the state's top disaster management official said. Fifteen others were injured.

"The death toll is likely to rise as many were critically injured," said A.K. Das, head of the authority.

The state has also been badly hit by floods and another three bodies were found in Jajpur district, taking the region's toll from the deluge to seven in 48 hours.

Torrential rains have wreaked havoc across several other Indian states, damaging roads and electricity networks, with nearly 700 reported dead across the country.

As many as 20 states have suffered in the current monsoon season that began in June.

In the western state of Gujarat, 213 people have been killed in weeks of flooding, state disaster management officials said.

The deaths almost doubled to its present level at the weekend when about 100 bodies were found after water started receding.

Suresh Kumar, West Bengal's top disaster management official, said at least 31 deaths were reported in a week of flooding in the state.

"Heavy rains have caused massive damage in several districts," Kumar said.

Landslides and flash floods in northeastern states since April have left dozens dead, while the eastern states of Jharkhand and Bihar have also been badly hit, with nearly 140 lightning deaths reported in Bihar since May.

Prime Minister Narendra Modi said in a radio address on Sunday that necessary help was being provided.

Lightning kills thousands of Indians every year, especially during the June-October monsoon, with most of them farmers working the fields.
