The hostages include Arbel Yehud - the civilian at the centre of a row which has led to Israel blocking the return of Gazans to northern Gaza.

Israel kept thousands of Palestinians from returning to their homes in northern Gaza as it accused Hamas of violating a fragile ceasefire by changing the order of hostages it has released.

Some troops had been expected to withdraw to allow hundreds of thousands of displaced Gazans to go home. But Israel said the hostage exchange before that step had not gone as agreed. Hamas accused Israel of stalling.
