ATLANTA — Atlanta’s zoo says a 19-year-old giant panda has given birth to a set of twins.

Zoo Atlanta said in a news release Saturday that the giant panda named Lun Lun delivered the twin cubs at 7:20 a.m. and 8:07 a.m. Saturday.

It’s Lun Lun’s second pair of twins.

Officials said Lun Lun was artificially inseminated in March. The round-the-clock birth watch started late last month.

Lun Lun and 18-year-old male panda Yang Yang have seven offspring together, all resulting from artificial insemination.

The pair’s first three cubs live at China’s Chengdu Research Base of Giant Panda Breeding. Twins Mei Lun and Mei Huan were born in 2013 and live at Zoo Atlanta.

Officials expect zoo members and guests to meet the cubs in December or early in January.
