Turkana

As the sun set over Lake Turkana, a mother sobbed and threw flowers into the greenish-blue water to remember her teenage daughter who had drowned trying to reach Kenya via a new route being used by people smugglers.

The fate of the two girls was put into the hands of traffickers who took them on a weeks-long trip by road and foot from Eritrea into neighbouring northern Ethiopia - then to the south into Kenya to the north-eastern shores of Lake Turkana, the world's largest permanent desert lake.

A female smuggler in Kenya confirmed to the BBC that Lake Turkana was increasingly being used as an illegal crossing for the migrants.

With Kenya having stepped up patrols on its roads, smugglers are now turning to Lake Turkana to get migrants into the country.

She plays 13-year-old Nawi, the eponymous heroine of the coming-of-age film set in Turkana county, a rural area which borders Uganda and where the UN says one in four girls are married before they are 18.
