What I have gathered from the live stream over the last hour or so:
(MOST OF THIS IS NOT VERIFIED - TAKE THIS WITH A BIG GRAIN OF SALT)
At least 4 (maybe up to 7) locations were attacked:
(1) A stadium in a suburb where a football match between France and Germany was taking place:
-> Apparently 3 explosions, 2 of them alledgedly by suicide bombers
-> 1 of these at the stadium entrance (apparently an attacker tried to get inside but was halted outside)
-> 1 explosion in a nearby Mc Donalds
(2) Attack on a concert hall:
-> Between 60-100 people were apparently attending the concert
-> Apparently 2-3 attackers without face masks opened fire with AK rifles within the building
-> The attack apparantly lasted at least 10-15 minutes
-> People first took cover, then many fled via an emergency exit, but there was no panic
-> [UNCERTAIN!] A wounded man from inside the building claimed that the attackers had started to kill people one-by-one
-> Police (GIGN?) stormed the building
-> 2 of the attackers apparently killed
(3+4) Drive-by(?) shootings at two restaurants:
-> Located very close to the concert hall (on the same road, apparently only a few hundred meters apart)
(5) An alledged shooting was reported from a shopping mall (no further info)
Reported: 40+ dead, 60+ injured, but that does apprantly not include any casualties from the concert hall (unverified sources claim 100+ dead there)
State of Emgergency has been declared, French borders closed down
Hospitals around Paris have enacted "plan white" (an emgergency plan to cope with a high number of injured people)
