A rescued migrant with a number on his right arm, sits on bus after disembark off the Italian Guardia di Finanza vessel Denaro at the Sicilian harbour of Catania on April 23, 2015. Calls have mounted for a military response to the Mediterranean migrant crisis, but experts say such plans are totally unworkable and mark an attempt to militarise what should be a purely humanitarian problem. European leaders will gather in Brussels to discuss new strategies in the wake of the latest disaster on April 19, in which hundreds of migrants drowned when their boat capsized on the way from Libya to Italy.
