(This second death has not been officially confirmed at this time.) One of the attackers was killed at the site, while the other apparently escaped.
Early on, there was speculation that the attack might have been an armed robbery, but France 24 reports that the gunman who was killed at the scene “was known to security services.” That appears to confirm the incident as a terrorist attack. (There are not, in any event, a lot of armed robberies carried out with Kalashnikovs on police cars.)
More, presumably, to come.
UPDATE: The most recent official report is that one police officer is dead and two seriously wounded.
FURTHER UPDATE: As always, early reports are at least partly wrong. Now officials are saying that there might only have been one attacker.Read more at PowerLineBlog
