RODRIGUEZ, Philippines (Reuters) - One by one, a mother and her children splash holy water over a white coffin barely a metre long. On the dirt floor beneath it lies a pair of tiny pink slippers.

This is a pauper's funeral mass in the Philippines for 3-year-old Myca Ulpina, one of the most recent - and the youngest known - victims of a war on drugs that has become so deadly and murky it is almost impossible to track how many have been killed.
