The hostage-taker announced at around 8:30 AM local time that he would surrender to police in 10 minutes, but instead killed both women and himself. Officers who stormed the building found all of them with severe wounds but were unable to save their lives.
At the moment, there is no official information about what exactly led to the shooting.
"A man took two women hostage and shot them in #Zurich. He then committed suicide. The motivations are unclear. Big police intervention in progress, sector cordoned off", the tweet says.
