New Delhi, India (CNN) -- At least 31 people were killed in a powerful storm that swept through parts of eastern India along the Bangladeshi border, officials said Wednesday.
The 45-minute storm packed winds up to 120 kph (75 mph), knocking down communication links in West Bengal state's North Dinajpur district after midnight, authorities said.
About 100,000 houses could have been damaged in the severe storm and feared that the death toll could rise, district official P.K. Dutta said.
Rescue operations were under way, and officials said they were trying to restore communications.
North Dinajpur district stretches along a 227-kilometer (141 mile) border with Bangladesh to the east and is home to 2.5 million people.
