Al-Jazeera Video: Syrian airstrike kills family in Aleppo

"Thousands of civilians are trapped by fighting between the army and opposition fighters in Syria. Many have fled to neighboring countries, but others cannot leave their homes. There have been calls for the setting up of safe zones inside Syria to protect people displaced by the violence. It will come too late for at least one family in the biggest city, Aleppo. Al Jazeera's Khadija Magardie reports."
