NAIROBI, Kenya - GlaxoSmithKline is giving Save the Children $23 million and entering into a five-year partnership with the charity to try to save the lives of 1 million children. The chief executives of the two groups visited a remote health clinic in Kenya on Thursday where they spoke to a mother who said she had three children die of diarrhea. Justin Forsyth, the head of Save the Children, said the mother told him and GSK chief executive Andrew Witty that she was devastated by the deaths, but was happy that her 5-year-old daughter was getting treatment for pneumonia.
