French authorities have released photos of two suspects who are still on the run after Wednesday’s terrorist attack at Charlie Hebdo headquarters in Paris that left 12 people dead.

Police say the men, identified as Said Kouachi and Cherif Kouachi, are brothers in their early 30s. Watch the video to learn more about them.

As a massive manhunt continues, police warn the men could be armed and dangerous. A third suspect, Hamyd Mourad, 18, is cooperating after surrendering to police 140 miles north of Paris. The suspects are possibly linked to al-Qaida.
