A video camera in the jungles of Indonesia has captured the first known footage of Sumatran tigers in the wild.
It has boosted efforts to conserve the endangered species, an environmental group said.
The video, shot in October 2009 on Sumatra, shows two year-old cubs and their mother approaching and sniffing the camera before moving on.
The World Wildlife Fund's tiger research team set up four video camera traps along well known tiger routes.
The routes allow the animals to move between two protected areas in central Sumatra, the Rimbang Baling Wildlife Reserve and Bukit Tigapuluh National Park. Karishma Vaswani reports.
