Transport trucks brought huge drilling equipment and pipes with rescue workers on Friday to dig a tunnel, trying to reach a two-year-old baby who fell into a deep well in southern Spain on Sunday.
"The priority now is to dig the vertical tunnel," said a spokeswoman for the Malaga municipal government.
Officials said on Thursday they had not lost hope of finding the baby alive, but it would take at least a few days.
Another tunnel is to be dug after rescue workers set up a platform to lift dirt and rubble.
The boy, named Gulin, fell in a well only 25 centimeters deep and 100 meters deep while his family was on a private plot in Totalan in Malaga.
The incident has attracted Spanish interest, and the whole country is holding breaths in anticipation of the rescue attempt.
The children's parents had a previous tragedy in 2017, when media reports said their three-year-old son died suddenly while walking on a beach near Totalan.
Interior Minister Fernando Grande Marlaska thanked public and private institutions Friday for "putting all their resources at our disposal" in what he described as a highly complex rescue operation.
