A metro train derailed in Istanbul just hours after its inauguration by President Recep Tayyip Erdoğan. The incident occurred on the new line connecting the city to the airport. At least three people were injured as a result of the derailment, though the extent of their injuries remains unclear. Authorities are investigating the cause of the accident, and service on the line has been temporarily suspended. The derailment raises questions about the safety of the newly opened transportation infrastructure. Emergency services responded to the scene and transported the injured to local hospitals. The incident occurred during what was intended to be a celebratory period for the city’s expanded public transport network.
