Mauritius says the UK's handing over of the long-contested Chagos Islands draws an important line under the archipelago's colonial history. The remote Indian Ocean islands were Britain's last African colony. The UK severed the Chagos Islands from Mauritius in 1965 and up to 2,000 Chagossians were expelled to make way for a military base. Mauritius says it's high time the colonial bullying was addressed. Now some Chagos islanders want to return to their ancestral home.
