Two young girls died after falling from their residential apartment when their parents were not at home on Sunday evening, eastday.com, a Shanghai news portal, reported.

Neighbors heard a loud noise at around 7 pm and found the girls lying on a second-floor terrace of a building on Fangxin Road in Shanghai's Pudong New Area. Medical practitioners confirmed the girls were dead.

The girls, aged 5 and 7, moved to the city with their parents from Anhui province and lived on the 13th floor of the building, police said after preliminary investigations.

Their parents, both born in 1980, were working at a restaurant nearby when the accident occurred.

Police have ruled out the possibility of homicide.
