PEREIRA: Rescuers raced in Colombia on Friday to free four people from a collapsed hotel, a rare sign of hope nearly four days after one of the strongest earthquakes to hit the Andean nation in decades left hundreds dead or missing.

The operation in the coffee-region city of Pereira had become the main focus of a disaster response increasingly shifting from the search for survivors to the grim work of clearing debris and accounting for the missing.

“My son is getting married on Sunday,” said Hernan Giraldo, the father of 24-year-old Juan Felipe, one of the people rescuers hope to save. “I’m waiting here to hug my son, alive. He was in that hotel room. I’ve been here since Monday night in case something happens, to find him.”

Venezuelan rescue workers, who arrived in Pereira after searching for survivors from the devastating twin quakes that hit their country’s Caribbean coast just seven weeks ago, were helping at the site with thermal imaging cameras.
