A North Korean murdered a Chinese family of three last year, Chinese media has said, the second recently reported killing of Chinese citizens by North Koreans. The incidents could strain ties between Pyongyang and its sole major ally.

The family was killed last September in a town in Jilin, which borders North Korea, the Beijing News said Tuesday.

The victims were a 64-year-old man, his 60-year-old wife and their 25-year-old son, the newspaper said, citing a relative, a man surnamed Yong. The North Korean man stole 500 yuan ($80), a handbag and two mobile phones, the paper said.
