What is life like for children in Israel and Gaza?
On Saturday, the Palestinian militant group, called Hamas, launched a surprise attack on Israel from an area called Gaza.
Israel responded by launching air attacks into Gaza, and Israeli troops are preparing to go into the area.
Gaza is a tiny strip of land, in between Israel and Egypt, nearly everyone who lives there is Palestinian, and it is controlled by Hamas.
The population is very young, almost half of the people living in Gaza, are children.
Charities and international organisations, like the United Nations, have called for children to be protected, whether they are Palestinian or Israeli.
