French media outlet Metronews reports that there's been a car explosion in front of a synagogue in Sarcelles, a city near Paris where two were two gunmen attacked the office of satirical magazine Charlie Hebdo just hours earlier. It is not clear whether the two events are connected. The Paris version of Metro reports that this event was an incident unrelated with the attack at the magazine. The car was parked in front of a synagogue, and reportedly exploded at about 2.30 p.m. local time (1.30 p.m. GMT).
