Why do 17,000 under-fives die daily?
A "staggering" number of children around the world are dying before the age of five, according to the United Nation's child agency.
Unicef' s latest figures estimate every day 17,000 under-fives die - 6.3 million a year - from largely preventable causes.
This is despite the overall rate of infant mortality having been halved in the past two decades.
Most of the deaths happen in the first hours or weeks following birth.
