I stumbled across this rally as I wandered around Istanbul. There was a large police presence outside this park to keep order. It was interesting to watch for a little bit, but my inability to speak Turkish hampered my ability to understand the particulars of this. I think the presence of Palestinian flags betrayed the general sentiment of the crowd.

The fountain on the right was a gift to the Ottoman Empire from Kaiser Wilhelm II (the one mocked in Allied World I propaganda) to commemorate his visit to Istanbul in 1898. It stands on one end of the former site of the Hippodrome of Constaninople. The street on the left runs along the course of the Hippodrome.
