The authorities in Egypt say they have broken up a ring of criminals who were involved in the trafficking of human organs.
Police have shut down a medical centre near the capital, Cairo, that specialised in kidney transplant, and have arrested a dozen doctors and members of staff.
The doctors are alleged to have removed organs from poor people, including some refugees, for use by wealthy Egyptian and foreign patients.
Seven years ago, Egypt criminalised the trade in human organs after the World Health Organization ranked it among the top five offenders in the world.
