Some settlers follow religious teachings which say a greater Israel should encompass all of Gaza and the West Bank, the Sinai peninsula in Egypt, Lebanon and parts of Syria and Turkey, and that their actions will speed up the coming of the Messiah.
Just 1,200 Jews lived in the West Bank before Israel occupied it in 1967. But 310,000 live there now in over 220 settlements, about half of which are said to be legal by Israel but all of which are illegal under UN conventions.
