A young Syrian swimmer and her 12-year-old brother have been killed by heavy shelling in Aleppo.

Mireille Hindoyan, a university student and sportswoman, was seriously injured and later died after bombs fell on the Villi district of the city, home to many people of Armenian descent.

Her brother Arman Hindoyan also died in the attack on Friday, according to Aleppo-based Armenian news service Kantsasar.
