There's growing pressure to end the violence in Gaza in the Middle East after at least 30 people were killed when a school was attacked by Israelis.
Israel has been bombing Gaza over the past 12 days because it says it wants to stop the armed group Hamas firing rocket missiles into their country.
So far, neither side is willing to back down but Israel has now said it will stop its attacks for three hours a day.
Here, Executive Director of Unicef David Bull explains to Sonali how much the charity can achieve in three hours.
