A dog given to South Korea by North Korean leader Kim Jong Un to promote peace has given birth to six puppies.

Two white Pungsan dogs were presented to South Korean President Moon Jae-in in September as a peace offering from North Korea to symbolize the two nations' warming relations.

One of the dogs, Gomi, recently gave birth to three female and three male puppies, Moon's office said on Twitter this week, adding that the president and the first lady were taking care of them.

The Blue House also shared a video of Moon with one of the dogs and a puppy.

South Korea described Gomi and the other dog, Songgang, as a "symbol of peace" when they arrived in September.

To get there, they had to undergo a quarantine and pass through the heavily fortified demilitarized zone and the so-called truce village of Panmunjom.
