Over the past decade/half-decade there has been growing support for right wing groups around Europe and France probably has the most volatile situation in that respect due to their largest Muslim population in the EU. The Front National, a very anti-immigration etc party, is 2nd/3rd in their polls and I can only see that growing before their 2017 elections. There's also quite a bit of popularity for that stance here in the UK, in the Netherlands, Italy, certainly Eastern Europe, and we saw the reaction to refugees in many places. Incidents such as these will only fuel that sentiment and I can't see anything but a return to the 1930s in the near future, except it won't be Jews who are the target.
Terrible events, I've been to Paris a few times, know people who travel there regularly. Don't feel in danger personally but they could really strike anywhere and I occasionally need to go to London in rush hour - always something in the back of your mind with the recent history. I'm afraid we're heading towards some dangerous times.
Some of the incidents yesterday were outside the stadium where France were playing Germany in a friendly. Next year France hosts Euro 2016 and I have to feel the atmosphere could be very tense then.
