The Blaze:

A gay couple in London is reportedly “devastated” after an alleged in vitro fertilization mix-up left them with two children from different racial backgrounds, NewsCore reported.

The couple said the allegedly botched treatment only came to light recently after their second child was born; they had wanted to use the same sperm donor again so their children would be genetically related.

“The damage to the [younger] child in the future, to both the siblings and the family unit could be quite catastrophic,” said Caron Heyes, the couple’s lawyer.
