EXCELSIOR (AP) - Authorities say several explosions have rocked a home in Excelsior, leaving the building engulfed in flames, but neighbors say they don't believe anyone was home.

The explosions happened about 3:55 p.m. Monday at the home on the 100 block of Lakeview Avenue, which is on Lake Minnetonka.

A message left by The Associated Press with the Excelsior Fire Department seeking more information was not immediately returned Monday afternoon.

Neighbor Michelle Koyama says she heard a huge boom and then saw flames shooting out of the house.

Neighbors say they believe the family had been spending time at their cabin.
