A woman here killed her two children by throwing them from a balcony of the 15th floor, investigators said.
"Suspect Galina Ryabkova was questioned and said she was fed up with the children, so she decided to get rid of them," investigative committee spokesman Vladimir Markin said.
A law enforcement source told RIA Novosti that during the questioning, the woman said her children - two boys aged four and seven - were now "angels in heaven".
Russian media suggested the reason for the murder was probably that the woman, who has been detained, had suspected her husband of cheating on her.
The family lived in a two-room apartment on the eighth floor. Ryabkova got to the 15th floor and threw her children from a balcony.
