A scuba diving trip in the Philippines ended in tragedy after one tourist was killed by sharks and another drowned when a powerful undercurrent separated them from their group. Ilia Peregudin, 29, was found “while being attacked,” with one arm severed and sharks “moving around him,” a Philippines coast guard commander told the Associated Press. Another diver with Peregudin’s group, 39-year-old Maksim Melekhov, was later found unresponsive at sea and was pronounced dead at a hospital. Peregudin had gone on the diving expedition south of Manila with his father Eduart Peregudin and his younger brother Timofy when the current pulled the group away from the designated site. While Ilia’s brother and father managed to surface and make it back to the boat with the dive instructor, Peregudin and Melekhov were lost to the sea. Authorities have launched an investigation into the tragedy and plan to meet with officials to discuss safety measures aimed at preventing future deadly incidents.
