Galina Ryabkova, 30, was arrested shortly after the incident, which took place on Sunday at the Moscow tower block in which she and her family lived.
The family live on the eighth floor of the building, but Ryabkova is believed to have taken the children up to the 15th floor before throwing them off. Her husband was away on business at the time.
Neighbours were alerted to the incident by the sounds of the childrens’ bodies hitting the hard ground
