Two stabbed near Charlie Hebdo’s old offices in Paris

French terrorism authorities are investigating a double-stabbing outside the former Paris offices of a satirical newspaper where a dozen people were killed in 2015, and two suspects have been arrested in Friday’s violence.

France’s counter-terrorism prosecutor said authorities suspect a terrorist motive because of the place and timing of the stabbings: in front of the building where Charlie Hebdo was based until the Islamic extremist attack on its cartoonists and at a time when suspects in the 2015 attack are on trial across town.

The suspects’ identities have not been released, and it is unclear exactly what prompted the attack.

An investigation was opened into “attempted murder in relation with a terrorist enterprise,” according to an official at the terrorism prosecutor’s office.
