Knife-wielding French man arrested at Eiffel Tower

A 19-year-old French man was arrested Saturday night for brandishing a knife at the Eiffel Tower, one of Paris' most popular tourist destinations.
According to various sources, the man - who was born in Mauritania - took out the knife and yelled 'Allahu Akbar' but did not injure anyone. Le Parisien, a French daily, has reported that the man had been in a psychiatric hospital.
The site was evacuated shortly after police arrested the man.
