A teenage girl has been auctioned off for marriage via Facebook in South Sudan, in what has been called a “barbaric use of technology” by children’s rights organisation Plan International.

The auction held for the girl (aged 16 or 17, her age is not yet verified) earned the family 500 cows, three Toyota Land Cruisers and $10,000 in dowry. Five men participated in the auction, some of whom were high ranking government officials, Plan International reported.

CNN broke the story this month, adding to the public relations woes of a digital giant already under attack from politicians demanding increased regulation of Facebook and other firms.
