if you're just joining us, there has been a flurry of activity outside paris this morning, explosions, gunfire, a major operation by french authorities on a certain street in a community outside paris called saint-denis. why were they there? they had reason to believe that the planner of friday's attacks may be not in syria as speculated but here, outside paris in an apartment on a street in saint-denis. they went to one apartment, then a second. they wound up encountering a team that at this point we know to have been at least equal in number, firepower and explosive capabilities to the one that launched the attacks on friday. a female inside, identified as a terrorist by authorities, detonated what they believe was certainly an explosive, maybe an additional explosionive vest.
