French terrorism authorities are investigating an attack that wounded at least two people near the former offices of the satirical newspaper Charlie Hebdo in Paris, authorities say.
A suspect has been arrested following Friday's attack, with reports the weapon used was a knife or an axe.
The area in eastern Paris remains cordoned off and children were being sequestered in nine schools while police worked to determine no other suspects were on the run, according to education and police officials.
It is unclear what motivated the attack or whether it was linked to Charlie Hebdo, which moved after its offices were targeted in a 2015 Islamic extremist attack that left 12 people dead.
Police cordoned off the area, including the former Charlie Hebdo offices, after a suspect package was noticed nearby, but the package was found to be harmless and no explosives were found, according a police official.
An investigation was opened into "attempted murder in relation with a terrorist enterprise," according to an official at the prosecutor's office. Authorities did not release the identity of the suspect arrested in the area of the Bastille Plaza.
"I saw a guy that was in his 30s or 40s with an axe in his hand who was walking behind a victim covered in blood...I cant tell you how many victims there was, I just saw one," witness Kader Alfa told The Associated Press at the scene.
AP reporters saw officers flooding into the neighborhood, near the Richard Lenoir subway station.
The two people confirmed injured worked for documentary film company Premieres Lignes, according to founder Paul Moreira. He told BFM television that the attacker fled into the subway, and the company's staff members were evacuated.
Moreira said a man in the street "attacked two people who were in front of the building, didn't enter the building, and who attacked them with an axe and who left." He said the company had not received any threats.
A Paris police official said that while authorities initially thought two attackers were involved, they now believe it was only one person, who was detained.
Police initially announced that four people were wounded in the attack, but the official told The Associated Press that there were only two confirmed wounded.
Police did not release the identities of the attacker or the wounded, who are in "absolutely urgent" condition, the official said.
French Prime Minister Jean Castex cut short a visit to a suburb north of Paris to head to the Interior Ministry to follow developments.
The trial in the Charlie Hebdo attacks is currently underway across town.
