Man behind Notre Dame attack was 'mature student not suspected of radicalisation'
The man who attacked police officers patrolling in front of Paris's Notre Dame Cathedral, shouting "This is for Syria!", was a mature student who had not been suspected of radicalisation, a French government spokesman has said.
Christopher Castaner told RTL radio on Wednesday that police were quickly able to classify the hammer attack as a terrorist act because of "the words he said".
An officer was slightly injured in the attack on Tuesday and the attacker remains in hospital after being shot by police.
No group immediately claimed responsibility for the incident, but police searching the man's residence outside Paris found a declaration of allegiance to the Islamic State group, according to the Paris prosecutor's office.
A student identity card showed he is from Algeria and 40 years old. He was reported to be working on his thesis for his doctorate.
