Swedish police prepared to storm the building, but before they had the chance to do so, the embassy was rocked by a series of violent explosions; the TNT had somehow been detonated. It turned out that one of the terrorists, Ulrich Wessel, had dropped a grenade, which killed him and detonated the TNT cache. The remaining hostages, as well as the other RAF members, all suffered severe burns. The extradition of the captured and surviving RAF militants was ordered by the Swedish then-Minister of Employment, Anna-Greta Leijon. Siegfried Hausner was flown back to West Germany, where he soon died of his wounds in Stammheim prison.
