Emergency workers are trying to pull a survivor from under the rubble of a nine-story building in Venezuela in a “miraculous” rescue operation eight days after the devastating earthquakes that hit the country.

Hernán Alberto Gil Flores, 44, who was buried under 29-feet of wreckage from a collapsed shopping mall parking lot in La Guaira, was in the process of being freed on Thursday amid a delicate days-long effort by local and international rescue teams.

Video shows the moment rescuers first made visual contact with Gil, who worked as a security guard at the mall, via a search camera fed into the collapsed basement of the building on Wednesday.

The man’s fingers could be seen waving though a small gap between layers of thick concrete and debris, in the video posted by the Chile Fire Department.

Emergency crews said they had been communicating with Gil and giving him water, food and medication, with fluids passed to him via a hose and syringe.
