A third pair of giant panda twins have been born in five days at a Chinese research base.
Seven-year-old mother Ni Ni gave birth to a pair of female cubs in south-west China's Sichuan Province.
The elder sister of the twins weighed 145.6g and the younger one 204.1g.
The Chengdu Research Base of Giant Panda Breeding said the mother and twins were all doing well.
The base now has 139 giant pandas and has bred 211.
China has more than 1,590 giant pandas in the wild and over 310 in captivity, zoologists say.
