Surveillance video obtained by The Associated Press indicates a team of three attackers carried out the shootings at a Paris sidewalk cafe, leading police to believe that a second assailant is on the loose.

Previously officials had not specified how many people were involved in the attack on the sidewalk bar on La Fontaine au Roi street.

Surveillance video of the shooting shows two black-clad gunmen with automatic weapons calmly firing on the bar, then returning slowly toward a waiting car, whose driver was maneuvering behind them.

Three French officials, who spoke on condition of anonymity because they were not authorized to comment on the investigation, confirmed that an analysis of the series of attacks on Friday indicated that one additional person directly involved in the assault remains unaccounted for.
