Rescue workers still hope to find survivors of the collapse of a large condominium building on an island community near Miami, Florida, on Thursday.Officials now say 10 people have died but more than 150 remain missing.Families of the missing have taken buses to an area nearby to watch the rescue effort, which includes using heavy equipment such as cranes.Rescue workers are using dogs and high technology devices in an effort to find people trapped in the wreckage and concrete.But, the search has been slowed by rain and a fire."We have over 80 rescuers at a time that are breaching the walls that collapsed," said Andy Alvarez on national television.He is a commander with Miami-Dade Fire Rescue. He said workers are looking in spaces left by the collapsed floors and walls."We have been able to tunnel through the building.This is a frantic search to seek that hope, that miracle, to see who we can bring out of this building alive."
