Following years of public outcry and campaigning by singer and actor Cher, Kaavan the elephant was set to embark on a journey from Pakistan to a sanctuary in Cambodia on Sunday.
The 35-year-old bull elephant's miserable condition in an Islamabad zoo had sparked an uproar from animal rights groups in the country and abroad.
A special cargo plane was arranged to transport Kaavan to a wildlife sanctuary in Cambodia, where authorities have made arrangements for his arrival.
The Cambodian sanctuary houses more than 80 elephants and is equipped with experts and other related facilities.
