Rescue specialists from the fire brigade’s elite EMAK unit work to free a worker who was buried up to his neck in mud when a broken water pipe caused the soil to collapse and the ensuing hole to begin filling up with water. The worker, identified as Petros Constantinis, and a colleague were digging a trench to lay down gas pipes in the Athenian district of Kolonos when a water pipe ruptured, causing the ground to collapse. The one worker was buried up to the waist and managed to fight free, but Constantinis could not move and was in danger of drowning. It took EMAK specialists three hours to free him. He was being treated in hospital. Officials said he was not in danger.
