Abdullah Kurdi, father of three-year old Aylan Kurdi, cries as he leaves a morgue in Mugla, Turkey, September 3, 2015. The family of Aylan, a Syrian toddler whose body washed up on a Turkish beach, had been trying to emigrate to Canada after fleeing the war-torn town of Kobani, one of their relatives told a Canadian newspaper on Thursday. A photograph of the tiny body of three-year old Aylan Kurdi washed up in the Aegean resort of Bodrum swept social media on Wednesday, spawning sympathy and outrage at the perceived inaction of developed nations in helping refugees. His 5-year-old brother Galip and mother Rehan, 35, also died after their boat capsized while trying to reach the Greek island of Kos. His father, Abdullah, was found semi-conscious and taken to hospital near Bodrum, according to Turkey's Sabah newspaper. (Photo by Murad Sezer/Reuters)
