A Facebook video was disseminated on the ISIS-affiliated website A'maq in which the attacker threatens that Euro 2016 would "be like a cemetery."

The video shows Larossi Abballa, a 25-year-old Islamic extremist, smiling eerily after making the threat. He admitted to killing the police commander, Jean-Baptiste Salvaing, and Jessica Schneider, a civil servant who worked at a local police station.
The attacker pledged allegiance to the leader of ISIS and made a call for Muslims to carry out jihad on so-called infidels.
