No European country can get out of taking in refugees who have the right to asylum, French President Francois Hollande said Saturday, amid a growing row over how to fairly distribute a massive influx of migrants across the continent.

The re-distribution "must involve all European countries -- no one can be exempt or we would no longer belong to the same union built on values and principles," Hollande said during a visit to Morocco, ahead of Wednesday's EU crisis summit on a contentious proposal to spread 120,000 refugees across member states.
