Eight radio-collared African cheetahs step out on to the grassland of Kuno National Park in central India, their final destination after a 5,000-mile (8,000 km) journey from Namibia that has drawn criticism from some conservationists.

The arrival of the big cats - the fastest land animal on Earth - coincides with the 72nd birthday of Indian Prime Minister Narendra Modi, who released the the first cat into the park on Saturday. It is the culmination of a 13-year effort to restore a species which vanished from India some 70 years ago.

The high-profile project is the first time wild cheetahs have been moved across continents to be released. It has raised questions from scientists who say the government should do more to protect the country's own struggling wildlife.

The cheetahs - five females and three males - arrived after a two-day airplane and helicopter journey from the African savannah, and are expected to spend two to three months in a 6-square-km (2-square-mile) enclosure inside the park in the central Indian state of Madhya Pradesh.
