Fourteen tiger cubs have been spotted in a reserve in north-western India, forestry officials say.

The sightings are a rare piece of good news in the fight to halt the steep decline in tiger numbers in India.

Forestry officials in Ranthambhore National Park in Rajasthan say the cubs are from several mothers and have been seen regularly in recent months.

Ranthambore had just 32 tigers at the last count. India is thought to have 1,500 tigers, half the world's total.
