Somalia government has condemned the abduction and rape of two girls aged just three and four.
The doctor in charge of the hospital where they are being treated also says they need major surgery.
Meanwhile, the Wednesday attack has led to several arrests of culprits.
According to the parents, 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.
Their parents desperately searched the neighbourhood and found them alone the next day.
BBC World Service Africa editor Will Ross says the fact that the girls are aged just three and four has added to the shock in Somalia where reports of rape have increased in recent years.
It is thought that such horrific crimes have long been taking place. But people are now more aware of the need to publicise the incidents in order to bring about change, he says.
