Anis Amri is likely the most wanted man in Europe right now.
Though several people could have been involved in Monday's attack on a Berlin Christmas market that left 12 people dead and 48 injured, Amri is the only suspect who's been publicly identified.
The 24-year-old Tunisian is considered violent and believed to be armed.
And according to German investigative files that CNN saw Thursday, Amri had previously discussed launching an attack in Germany.
Here's what we know about him.
