Mystery Lake Appears Overnight in Tunisian Desert: Scientists Warn 'Stay Away!'

• A mysterious lake, spanning one hectare and 18 meters deep, appeared overnight in 2014 in the Gafsa desert, Tunisia.
• Initially seen as a miracle, scientists believe it formed due to an earthquake or geological activity, pushing underground water to the surface.
• The Gafsa region is a phosphate mining hub, leading experts to warn that the lake water is contaminated with radioactive phosphate residues.
• Despite warnings from public safety officials about the fatal risks, thousands initially flocked to swim in the lake due to the desert heat.
• The lake's color changed from blue to green, indicating stagnant water and algae growth, and its water level has significantly dropped, making it highly unsafe.
