A seven year old panda has given birth to twin female cubs at the Chengdu Giant Panda Breeding Research Centre in the Sichuan province on 22 June.

According to the research chief Zhang Zhihe, they are the first panda twins born this year in the world.

"Both cubs are female and weigh 118 grams and 70 grams respectively. They are healthy and their mother Ke Lin tried to embrace them after their birth," he said, according to China Daily.

In January, researchers artificially inseminated Ke Lin and she started showing signs of being pregnant late last month, Zhang said.
