Conservationists have discovered a new population of the critically endangered Indochinese tiger in a Thai jungle.
There are believed to be less than 250 of the global population remaining due to poaching and loss of habitat.
Cameras set up in a national park in eastern Thailand captured over five tiger cubs on film.
The only other known breeding ground for the species, which are smaller than the better-known Bengal and Siberian tigers, is in the Huai Kha Khaeng Wildlife Sanctuary in western Thailand.
The numbers of tigers in the wild have fallen drastically from 100,000 a century ago to just 3,900 today largely because of poaching, say conservationists.
It is feared that the animal, which once ranged across much of Asia, are now all but extinct in southern China, Cambodia, Laos, Vietnam and much of Myanmar.
Anti-poaching organisation Freeland and wild cat conservation group Panthera carried out the tiger survey in partnership with the national park authorities.
"The Thai forestry department proved that with protection you can not only bring tigers back, but now the western forest complex, specifically Huai Kha Khaeng, is a global model of tiger conservation," said Alan Rabinowitz, chief executive officer of Panthera.
"It is one of the best protected and best tiger areas left in the world," he added.
