In the East of Nairobi,
lies one of the largest informal settlements.
Here, children have to content with filth and...
lack of transport facilities.
These siblings were photographed on Aug 14...
as they crossed this sewer-filled river from...
Mukuru kwa Reuben to Mukuru Kwa Njenga.
The elder boy had to strap his sister to his back,
and wade across, stopping severally to take rest.
When across, he went back to help another kid.
