Aksaray Square in Istanbul has been called "smugglers square". It is there that migrants gather almost every day at sundown in the hope of buying a place on a boat to Greece.
Their belongings are stuffed into plastic bags so too are life jackets which they buy at the square..
The park is central to the human trafficking business and the trade is good despite pressure on Turkey to crack down on it.
Among the smugglers are Syrians, including Ali.
