As the last troops left, thousands of Palestinians arrived, firing guns into the air and lighting fires.
Unlike Gaza, Israeli forces will carry on patrolling the area and will not hand over control to the Palestinians.
It is the first time Israel has removed long-established settlements from land claimed for a future Palestinian state.

More than 400,000 settlers remain on occupied land claimed by Palestinians for their future state.
