Colombia starts sterilising hippos descended from drug kingpin Pablo Escobar's pets
The hippos spread from Escobar's estate into nearby rivers, where they flourished.
There are now more than 100 of them, prompting the government's plan to control the population.
Two male hippos and one female have been surgically sterilised, environmental authorities said.
The government plans to sterilise 40 hippos a year, transfer others to different countries, and may euthanise some of the animals.
