Building Explosion in Athens' Plaka District Kills Six Including Four American Tourists After Suspected Gas Leak Causes Collapse

Six people were killed when a powerful explosion caused a residential building to collapse in Athens' historic Plaka district on Friday morning, September 25, 2026, according to Greek authorities. Rescue crews recovered the last two bodies from the rubble on Saturday afternoon after a search lasting more than 24 hours. The victims included four American tourists who were staying in a short-term rental apartment and an elderly couple, a 77-year-old British man and a 78-year-old Greek woman, who lived in the building. Athens Mayor Haris Doukas said the explosion was likely caused by a major gas leak. The blast struck the building on Lysikratous Street shortly after 7:30 AM on Friday, near the Acropolis, causing much of the structure to collapse and damaging neighboring buildings and parked vehicles. Two women in an adjacent building were injured with non-life-threatening injuries. US Ambassador to Greece Kimberly Guilfoyle expressed deep appreciation to Greek first responders and said the embassy is providing consular assistance to the victims' families. The incident highlights ongoing infrastructure risks in Athens' older residential districts, where aging gas supply systems and historic building stock create persistent safety challenges. The mayor said two nearby buildings were left in a dangerous state and inspections are underway to determine if they can remain standing or must be demolished. For US travelers, the event serves as a reminder of infrastructure risks in older European city centers, particularly in short-term rental properties that may lack modern safety systems. Greek authorities have opened an investigation into the cause of the explosion.
