"Extensive executions have been carried out for relatives of Jang Song-thaek," one source told Yonhap. "All relatives of Jang have been put to death, including even children."
On December 12, Kim Jong-un executed his uncle and his close allies for "acts of treachery," which may have related to a business dispute.
Yonhap is known for its anti-North Korean bias. And other stories about the purge are probably fake.
Nevertheless, Kim's ruthlessness cannot be discounted.
From Yonhap:
The executed relatives include Jang's sister Jang Kye-sun, her husband and Ambassador to Cuba Jon Yong-jin, and Ambassador to Malaysia Jang Yong-chol, who is a nephew of Jang, as well as his two sons, the sources said.
All of them were recalled to Pyongyang in early December and executed, they said. The sons, daughters and even grandchildren of Jang's two brothers were all executed, they said.
It is unclear if Jang's wife, who is the younger sister of Kim's father, Kim Jong Il, is among those ordered executed.
