French counterterrorism forces stormed an apartment in a Parisian suburb just after four in the morning local time. 

When authorities entered, a woman inside the flat triggered a suicide blast. When another man tried to flee, he was cut down by snipers. 

Police arrested at least seven people before the end of the night. 

In the wake of last week's mass attacks in Paris, authorities are in a race against time to track terror cells and prevent more attacks. But Errol Southers, a counterterrorism expert at USC, says the recent raids reveal some troubling details about the capabilities of the extremist network, and that American officials should take notice.
