Several people were injured in an attack near the offices of French satirical magazine Charlie Hebdo on Friday.
At least four people were injured.
Two are apparently in a critical condition.
The victims were reportedly attacked with a knife.
Police are maintaining high visibility in the area, while apparently searching for more attackers.
The Telegraph reported that the attack comes amid the trial of the alleged accomplices who were involved in the January 2015 attack on reporters and artists of the magazine and in which 12 people were killed.
A cartoon of the Prophet Mohammed that was published by the magazine and allegedly unleashed the attack was recently re-published shortly before the trial began.
Following the publication of the cartoons in 2006, jihadists warned online that they would pay for the portrayal of Mohammed. To Muslims, any depiction of the Prophet is blasphemous.
Al Qaeda’s branch in Yemen put the then director of Charlie Hebdo on its list of “wanted people”.
Update: French Prime Minister Jean Castex had earlier said four people had been stabbed, but a police source later confirmed to Reuters news agency that two people had been injured during the attack, one of whom was in a serious condition.
According to The Spectator Index, a suspect has been arrested.
