To keep it as neutral as possible:
There's a big referendum coming up in Turkey next month, effectively giving Erdogan even more power if some law or change or something is approved via that referendum. Obviously he wants everyone to vote yes, so he's sending his ministers all over Europe (well, countries like the Netherlands, Germany, Switzerland, you know, where a lot of Turkish people can be found) to campaign for the 'Yes' camp.
I believe Switzerland is allowing it, but Germany started refusing some ministers and now the Netherlands is doing the same. Saturday one of them was supposed to hold a public speech near the Turkish consulate, but in the days leading up to that, Dutch politicians (including the minister of Foreign Affairs) were making it more and more clear they did not want them to do that here. Then on the day she arrived, they didn't give her plane permission to land and she had to drive via Germany. In Rotterdam, her convoy was stopped and she wasn't allowed to go to the place where she'd have her speech.
This whole thing eventually resulted in a couple hundreds of Turkish people living in the Netherlands gathering near the consulate, protesting and stuff. Apart from some small unrest, luckily it didn't turn as violent as one could have expected, so that's good. The Turkish minister of course was angry ("you're breaking all laws!"), Wilders of course was as happy as a child in a candy store ("Leave this country and bring all those fans of yours with you!") and Erdogan called the Netherlands 'remnants of the nazis' or something similar and is now promising sanctions and everything (which nobody here really cares about...at all. These sanctions would have just as much effect as when I tell you that if you don't listen to me, you won't be allowed to watch the Dutch high school bog snorkling championships).
I'm sure I forgot some things but to the best of my limited knowledge when it comes to politics, this is about it
