Fake terrorists released imaginary toxic gas in a busy Parisian subway station early Thursday as the French capital conducted its first full-scale terrorist exercise.
The simulated terrorist attack was aimed at practicing emergency procedures for the first time since the September 11, 2001 attacks on the United States.
Five-hundred police, firefighters, and emergency crews participated.
Two phony terrorists spilled their fake sarin gas just after midnight local time in the Invalides Metro station.
Volunteers played victims with signs around their necks describing their alleged symptoms.
The exercise ended with police capturing the two mock terrorists.
