French authorities launched an anti-terrorism investigation Friday after an attacker stabbed two people in Paris near the former offices of the satirical magazine Charlie Hebdo.
Paris police said they arrested two people, including one taken into custody in the Place de la Bastille square area, not far from where the attack took place.
Authorities initially said four people were wounded, but later revised the figure to two.
The motivation for the attack and whether it had any connection to Charlie Hebdo is unclear.
Islamist militants attacked the Charlie Hebdo offices in 2015, killing 12 people.
A terrorism trial for 14 people accused of being accomplices in that attack is currently going on in Paris.
Charlie Hebdo angered many Muslims by publishing cartoons featuring the Prophet Muhammad, and ahead of the trial it recently reprinted some of the same cartoons.
Last week, police moved the magazine's head of human resources from her home after she was the target of death threats around the start of the trial.
