This story from the BBC is sad:
Healthy new-born babies may have been killed in Ukraine to feed a flourishing international trade in stem cells, evidence obtained by the BBC suggests.
Disturbing video footage of post-mortem examinations on dismembered tiny bodies raises serious questions about what happened to them.
Ukraine has become the self-styled stem cell capital of the world.
There is a trade in stem cells from aborted foetuses, amid unproven claims they can help fight many diseases.
But now there are claims that stem cells are also being harvested from live babies.
