HAVANA -- (AP) -- A gas explosion at a home in the Cuban capital killed seven people, including two children, state television reported Thursday evening.

One person suffered burn injuries. A home was destroyed and two others were damaged, the regular nightly news program said.

Authorities were trying to determine the exact cause of the accident in Havana. A preliminary investigation found evidence of ``imprudence'' in the storage and handling of the gas, the program said.
