'World's loneliest elephant' heads to Cambodia after Cher campaign

Kaavan, an overweight 36-year-old elephant, to be rehomed after outcry at conditions

After years of public outcry and campaigning by the US singer and actor Cher, the world's loneliest elephant" embarked on Sunday on a mammoth move from Pakistan to retirement in a Cambodian sanctuary.

Cher has spent recent days at the Islamabad zoo to provide moral support to Kaavan - an overweight 36-year-old bull elephant - whose pitiful treatment at the dilapidated facility sparked an uproar from animal rights groups and a spirited social media campaign.
