Gas leak explosion in Athens kills four Americans, two others

An explosion believed to have been caused by a gas leak destroyed a building in central Athens on Monday, killing six people including four American nationals, authorities said. The incident occurred in the Plaka district, one of the Greek capital's most visited heritage areas, drawing emergency responders to the densely populated neighbourhood. Two women sustained injuries in the blast that left the structure in ruins, according to emergency services. Rescue teams worked to secure the site and investigate the cause of the explosion. The identities of the victims and the injured were not immediately disclosed. Investigators are examining whether the gas leak originated from the building's supply system or nearby infrastructure.
