A court in Spain on Friday convicted a Spanish couple of drugging and suffocating their 12-year-old adopted Chinese daughter, in a case that has drawn the attention of Beijing.

Rosario Porto, a former lawyer, and her ex-husband, journalist Alfonso Basterra, had been accused of drugging Asunta, whom they adopted when she was a baby, with the sedative Orfidal periodically for three months and finally asphyxiating her in September 2013.
