Six dead in Athens building blast; what caused it remains unknown

For more than a day, the news from a collapsed building in central Athens came in the language of a search: first one woman recovered, then five people still missing. By Saturday afternoon, September 26, there was no one left to find alive. The Greek Fire Service said all six people missing after Friday’s explosion in the Plaka district had been recovered dead. That completed the recovery, not the investigation. Families still had no confirmed explanation for the blast. ^{13 18}

The explosion struck at about 7:30 a.m. Friday at 15 Lysikratous Street, in the historic neighborhood near the Acropolis. Excavators removed wreckage as crews searched the collapsed building; an early account described roughly 30 firefighters working with rescue dogs, though later reporting did not independently establish the staffing figure. At a 3 p.m. Saturday briefing, the Fire Service confirmed that all six missing people had been recovered. More than 24 hours had passed since the blast. The dead were reported as three women and three men. ^{26 13 18 1}

That sequence matters. The account of one body and five missing was a report from midway through the search, not a competing death toll. It does not establish when each of the remaining victims was found. Nor is every physical detail of the building settled: most reports describe it as two storeys, while some describe three. Its pre-collapse height should not be treated as a finding about why it fell. ^{13 18 1 2}

The deaths have been reported well beyond Greece. The Guardian described four of those killed as American tourists and said a British man and his Greek wife, reportedly aged 77 and 78, were also among the dead. But the Fire Service had not announced a verified list of the six names and nationalities. Greek state media, as reported by the Associated Press, said documents and belongings found with four victims indicated U.S. citizenship. Such belongings are evidence for investigators, not formal identification. DNA comparisons with relatives were still being sought as of September 27. ^{1 2 29}

Other reports have supplied more personal descriptions, including American-Albanian siblings and their spouses and a tourist said to have been pregnant. Those details have not been formally confirmed and should not stand in for identified victims. The same caution applies to early reports that American short-term renters were among the missing: those were provisional accounts made while rescuers were still at work. ^{20 22 13}

The Guardian reported at least three people injured. An earlier NBC News broadcast reported at least two; its figure was an earlier lower bound, not evidence of a separate change in the number hurt. Another account described women evacuated from an adjoining building, without clearly establishing that both were injured. There is no reconciled final injury count. ^{1 16 13}

Athens Mayor Haris Doukas said a major gas leak was believed to have caused the explosion. Reporting has also pointed to a possible origin in a second-floor apartment. Neither is a determination. A co-owner of an Airbnb rental said the rental had no gas supply. That claim does not establish what installations existed elsewhere in the building, whether any were working or what ignited the blast. ^{2 21 27}

Gas distributor Enaon EDA sent response crews to the property on September 25 to carry out checks with the authorities. Its statement was careful about what those checks could establish: ²⁶

Company representatives subsequently said checks of the external natural-gas distribution network had found no leak by late Friday. That is a finding about the outside network, not a clearance of any internal installation or proof that gas from another source was involved. As of September 27, a ten-officer Fire Service specialist arson-investigation team was examining and documenting the wreckage and collecting evidence. The team’s involvement does not amount to a finding of arson. The building’s age has also been raised in reporting, but no established finding ties it to the collapse. ^{46 28 21}

There is a separate question about warnings before the explosion. On September 26, Ta Nea reported residents’ claims that they had warned of a gas odor. Fire Service spokesman Brigadier General Vasilis Vathrakogiannis said his service had received no complaint about a gas smell in the area before the incident, as iefimerida reported. The accounts leave unresolved who, if anyone, received a warning and when. A reported odor cannot, by itself, establish the source of the explosion. ^{59 58}

The disaster has revived a debate already underway in Plaka about short-term accommodation. Giorgos Zafeiriou, an architect who heads a local residents’ committee, said the explosion would intensify questions about who inspects holiday rentals. Greece’s government had pursued permit restrictions and tighter controls on Plaka short-term lets amid a housing crisis. Those policy questions deserve answers, but no inspection result for this building has been established, and there is no finding that a rental or a failure to inspect one caused the blast. ¹

The recovery operation has answered the first terrible question: six people died. The work still capable of explaining their deaths is more exacting—formal identification, a reconciled injury count and forensic examination of the wreckage and any gas installations. Until then, a mayor’s suspicion, a distributor’s finding about its outside network and residents’ accounts of a smell are pieces of an inquiry, not a settled cause. ^{18 29 46}
