What is the Gaza Strip?
Gaza is a small Palestinian region on the Mediterranean Sea that borders Egypt and Israel. It covers 360 square kilometres and is densely populated with about 1.8 million people.
After the First World War, Gaza became a part of the British Mandate of Palestine. It was later administered by Egypt following the Arab-Israeli War in 1948.
The Gaza Strip was captured by Israel during the 1967 Six-Day War and, decades later, transferred to the Palestinian Authority under agreements signed in the 1990s.
Israel occupied the Gaza Strip until 2005, when it withdrew its military outposts and thousands of settlers.
Hamas, an Islamic organization that won the Palestinian legislative election in 2006, has been controlling Gaza since 2007. West Bank, the other, separate Palestinian territory in the region, has been governed by the Palestinian Authority.
Earlier this year, Hamas and Fatah, the leading Palestinian political party operating out of the West Bank, signed an agreement to form a united Palestinian government.
What is Hamas and how did it come to power in Gaza?
Hamas, or the Islamic Resistance Movement, was founded in 1987 as a Palestinian branch of the Egyptian Muslim Brotherhood. It is considered a terrorist organization in many countries around the world, including Israel, U.S. and Canada.
In early 2006, Hamas won the Palestinian parliamentary elections. At that time, attempts to unite Hamas and Fatah failed, with Hamas taking control of all military and government institutions in the Gaza Strip.
Hamas has been waging a war on Israel, while refusing to recognize the Jewish state.

The military also said it wants to stop Hamas militants from infiltrating Israel through tunnels that cross the Israel-Gaza border.
Hamas has been using the underground tunnels -- some of which cross the border with Egypt -- to get weapons, materials and goods.
But because of Israel and Egypt鈥檚 blockade of Gaza, civilians also use the tunnels to get food and medical supplies.

Israel鈥檚 last ground invasion took place during the Gaza War in January 2009. The brief war, also known as Operation Cast Lead, resulted in the deaths of more than 1,000 Palestinians. The total number of reported casualties has varied, depending on the source.
What does this all mean for the people of Gaza?
