Colombia has said that the cost of transferring 70 hippos that belonged to deceased drug lord Pablo Escobar to overseas sanctuaries will be $3.5m.
The cocaine baron brought a small number of the animals from Africa to Colombia in the late 1980s. But after his death in 1993 the animals were left to roam freely in a hot, marshy area of Antioquia department, where environmental authorities have been helpless to curb their numbers.
