and take ground in the West Bank and Gaza Strip, establishing the Palestinian National Authority. The peace process also had significant opposition among radical Islamic elements of Palestinian society, such as Hamas and Palestinian Islamic Jihad, who immediately initiated a campaign of attacks targeting Israelis. Following hundreds of casualties and a wave of radical anti-government propaganda, Israeli Prime Minister Rabin was assassinated by an Israeli fanatic who objected to the peace initiative. This struck a serious blow to the peace process, from which the newly elected government of Israel in 1996 backed off. Following several years of unsuccessful negotiations, the conflict re-erupted as the Second Intifada in September 2000. The violence, escalating into an open conflict between the Palestinian National Security Forces and the Israel Defense Forces, lasted until 2004/2005 and led to approximately 130 fatalities. In 2005, Israeli Prime Minister Sharon ordered the removal of Israeli settlers and soldiers from Gaza. Israel and its Supreme Court formally declared an end to occupation, saying it "had no effective control over what occurred" in Gaza. However, the United Nations, Human Rights Watch and many other international bodies and NGOs continue to consider Israel to be the occupying power of the Gaza Strip as Israel controls Gaza Strip's airspace, territorial waters and controls the movement of people or goods in or out of Gaza by air or sea.

After internal Palestinian political struggle between Fatah and Hamas erupted into the Battle of Gaza (2007), Hamas took full control of the area. In 2007, Israel imposed a naval blockade on the Gaza Strip, and cooperation with Egypt allowed a ground blockade of the Egyptian border The tensions between Israel and Hamas escalated until late 2008, when Israel launched operation Cast Lead upon Gaza, resulting in thousands of civilian casualties and billions of dollars in damage. By February 2009, a ceasefire was signed with international mediation between the parties, though the occupation and small and sporadic eruptions of violence continued. In 2011, a Palestinian Authority attempt to gain UN membership as a fully sovereign state failed. In Hamas-controlled Gaza, sporadic rocket attacks on Israel and Israeli air raids still take place. In November 2012, the
