Why are migrants choosing Alexandria?

The UK will not support future search and rescue operations to prevent migrants drowning in the Mediterranean Sea, the Foreign Office has said.

An Italian mission is being wound down and an EU force will carry out a more limited border security operation.

Around 150,000 migrants - mostly from northern Africa and the Middle East - have been rescued by Italian ships over the past 12 months - and this year alone, some 3,000 migrants have drowned.

Orla Guerin reports from Alexandria, in Egypt where a growing number of migrants begin their journey.
