Paris – An administrator armed with a knife attacked officers inside Paris police headquarters Thursday, killing at least four before he was fatally shot, officials said.
Police union official Loic Travers told reporters the attack appeared to have started in an office and continued elsewhere in the large police compound across the street from Notre Dame Cathedral.
The number of people injured was not immediately known.
Travers said the motive is unknown, but that the 20-year police employee allegedly responsible for the attack worked in the intelligence unit and had not posed known problems until Thursday.
He said he could not remember an attack of this magnitude against officers.
