TBH Dazzer, unless you go well off the path, you're very unlikely to encounter anything like this.
This happened 440 miles away from Noukchott, which is where most people travelling through Mori on there way to proper black Africa will pass through.
The area it occurred in has always been a bit iffy, it's where the Polisario radicals hide out (and I wish their story was better known......say no more) and there are a lot of lawless elements in that area.
We've seen lots of police activity near borders, crossed minefields and have seen guns worn fairly openly on streets, but unless you really go out of the 'normal' routes ,you really won't come across it..it's not a particularly 'interesting' area (most people will have their fill of the proper desert in a few days playing around Tan Tan or Merzouga or Mhamid) and again, the area this happened in isn't one you'd normally cross if you were aiming for Senegal, Gambia or anywhere further south.
Put it in perspective.....how many people were killed in the UK over the new year???
Dazzer, sensible words which put things into perspective from Fanum here.
I'm assuming you're planning riding down the Atlantic route (as am I in a few weeks time). You have to accept there's always an element of risk in any venture taking you outside of your usual comfort zone, and if you're anything like me, that's a small part of the reason we do it.
These incidents, very disturbing though they are, occurred way outside the north - south route between the Western Sahara and the Senegal border.
As regards the rally, like others, feel great sadness for all concerned, the competitors, the spectators but most of all for the people of N.W.Africa for whom the rally stood to inject a needed boost into their local economies.
As was said on the radio late on today, travel in Algeria, Tunisia, and parts of Mali has been problematic for some time. Now Mauritania, for the moment at least, looks like it may be joining them. Not a very cheering thought!
BTW. For Christmas my daughter bought me
"Endgame in the Western Sahara" (Toby Shelley) Makes for some very interesting reading, though not finished it yet.
