It is home to more than 1.4 million Palestinians and officially controlled by Israel. Why? Why are the two sides fighting? There has been tension between Israelis and Palestinians for decades. Although Israel withdrew its troops in 2005, Hamas wants total liberation from Israel's control. How? How can the situation be resolved? With Hamas frequently firing rockets into Israel and causing disruption, and Israel retaliating with shells and rockets which have killed large numbers of Gazans in recent months, the end of the dispute still seems a long way off.
