Rescuers in Kenya have retrieved the body of a teenager who drowned as she tried to save a man who had got into trouble as he was crossing a swollen river.

Anna Nduku, 19, fell into the Kandisi river near Ongata Rongai, on the outskirts of the capital, Nairobi, on Tuesday.

She is one of more than 130 people who have died as a result of the flooding caused by the heavy rains that have been falling since October.

Ms Nduku was responding to the cries of help of a man who was clinging to part of a bridge that was under construction.

The man survived but as she tried to save him she fell into the river.
