Spanish rescuers are drilling a 260-foot long horizontal tunnel into the side of a mountain to reach a toddler who's been trapped for three days.
It will take workers about 48 hours to complete the drilling, and then they'd have to connect it with the bottom of the well where the 2-year-old boy, named Julen, is located, Diario Sur reported.
Authorities told El Pais rescuers are also working on drilling a vertical tunnel running parallel to the shaft.
Wednesday, authorities found traces of DNA in the soil near the water well, eliminating questions about whether a child could've fallen into it. It measures about 10 inches wide and is 360 feet deep.
Rescue efforts slowed Monday after equipment became stuck in the well. Rescuers, including teams of miners and heavy machine operators, are concerned the well could collapse.
"My cousin, who was closer, followed him and started to cry 'the child, the child' as she was afraid he would stumble," Rosello said.
