On 25 July 1995 a gas bottle exploded in the Saint-Michel station of line B of the RER metropolitan train system in Paris. Emergency service vehicles then used Place Saint-Michel and the surrounding bridges and streets to attend the scene, while Parvis Notre-Dame became a helicopter landing site and a nearby café, "Le depart Saint-Michel", was used as a field hospital. At 8:00 that evening, national news on France 2 announced that four people had been killed and another 40 injured in a "mysterious explosion". At that time, no official sources had confirmed that it was a terrorist attack. This was only confirmed later, and the final outcome was said to be eight deaths and 117 injured. It was the deadliest terror attack in France since the 1983 Orly Airport attack, and would be the only deadly attack for the GIA's 1995 bombing campaign in France.
