Misrata's injured treated in Benghazi
Nato has said there is only so much air forces can do to protect civilians in the besieged city of Misrata in Libya.
The United Nations says at least 20 children have been killed in attacks by government forces on rebel-held parts of the city.
The BBC has been meeting some of the injured children and rebel fighters who escaped from Misrata to rebel-held Benghazi.
