The government in Somalia has denounced the abduction and rape of two girls aged just three and four, reports the BBC.
The doctor in command of the hospital where they are being attended states they require significant surgery.
An official announced several arrests had been made after the assault which happened on last Wednesday.
The parents maintain that the two cousins were walking home from school in Afgoye, close to the capital, Mogadishu.
They were seized by men who took them away and sexually assaulted them, adds the BBC.
Their parents frantically searched for the neighbourhood and discovered them alone the following day.
