Soldiers in Myanmar, the country formerly known as Burma, are forcing Rohingya refugees to build a barbed wire fence on the Bangladesh border.
The fence they are building is designed to stop their own people from moving across the border.
Inside Bangladesh, Rohingyas are being persecuted and kept in miserable holding facilities. They cannot go home, they are not officially recognised as asylum seekers and they have nowhere to go.
Myanmar's security forces are overseeing construction of the barrier.
