Well, the detainment of Ivan Watson was just the aperitif for the anniversary of the Taksim Square protests. At the site of last year's protests, as many as 25,000 policemen amassed to enforce a ban on demonstrations at the square, which set off sustained protests in which thousands were injured and a number of people were killed.
This time around, hundreds of demonstrators attempted to march on the square despite the ban and were met by police who used water cannons and tear gas to clear the crowds. Here's a (n unpleasant) video of the happenings from AFP:
