Up to 20,000 people gathered in Istanbul on Thursday to pay tribute to the nine activists killed in the attack. The coffins were carried through central Istanbul draped in Turkish and Palestinian flags. The youngest of the nine victims was nineteen-year-old US citizen Furkan Dogan. Dogan was born in Troy, New York and moved to Turkey when he was two years old. An autopsy showed he was shot at close range, once in the chest and four times in the head.
