Failed asylum seekers who are rejected by their home countries will be deported to new camps in Africa under plans being examined by European Union leaders.
Economic migrants who were deemed to have no right to stay in Europe but whose country of origin refuses to issue them landing papers could be sent to live in "regional" centres in nearby countries.
EU interior ministers agreed to study the plans after they were promoted by Theresa May, Britain's Home Secretary, at a Luxembourg summit.
The ministers discussed a tough new approach to the migrant crisis, pledging to deport tens of thousands of economic migrants who have arrived alongside genuine refugees.
The plans include locking up more people who face deportation to prevent them from disappearing, and expanding existing detention centres.
