An image of a drowned toddler washed up on the beach in one of Turkey's prime tourist resorts swept across social media on Wednesday after at least 12 presumed Syrian refugees died trying to reach the Greek island of Kos.

The picture showed a little boy wearing a bright red T-shirt and shorts lying face-down in the surf on a beach near the resort town of Bodrum. In a second image, a grim-faced policeman carries the body away.

Turkish media identified the boy as 3-year-old Aylan Kurdi, whose 5-year-old brother died on the same boat. Media reports said he was from the north Syrian town of Kobani near the Turkish border, scene of heavy fighting between Islamic State insurgents and Kurdish regional forces a few months ago.
