Several videos showing the gunmen outside the office of Charlie Hebdo, a satirical newspaper, have surfaced online. The footage includes scenes of graphic violence.
ISIS has claimed responsibility for the worst violence witnessed in France since World War II, a volley of nearly simultaneous terror attacks that the French President called “an act of war.”
The assailants targeted six sites Friday night in Paris, the deadliest being a massacre at a concert hall where at least 80 people were killed.
In all, French authorities put the number of dead at 128, though the death toll is expected to fluctuate as the situation becomes clearer.
The threat of ISIS is well-known, with the jihadist group’s atrocities in Syria and Iraq being met with condemnation and airstrikes by a U.S.-led coalition that includes France.
