Rain and thunderstorm, as forecast by the weather office, hit most of the northeastern states from early Tuesday.
At several places tin-roofed houses, shops and other facilities were flattened by the thunderstorms. Some people who were asleep were injured by the flying corrugated iron sheets and crumbling portions of the houses.
Talking to ISTV, a local cable network, Manipur Chief Secretary Oinam Nabakishore said: "Now that it is confirmed that houses and other facilities have been destroyed, the government has sought detailed reports from the district administrations. Once the reports are with the government, it will be seen what can be done for the victims."
"Money for the relief will be set aside from the state disaster relief fund," Nabakishore said.
In Manipur, the thunderstorm hit many places in the early hours of the morning when most people were still asleep. The hill districts were worst affected.
Many trees fell or were uprooted along the state and the national highways, blocking traffic and causing long hours of snarls.
