Libyan authorities are struggling to cope with a post-revolution influx of migrants, many of whom are using the Mediterranean country as a stepping stone to Europe.

Mustafa Joha, the commanding officer of Tripoli's naval base, says that the country's coastline is too vast to patrol effectively, especially since NATO forces destroyed most of its ships during the country's war.

And he says European countries should be doing a lot more to help: "Let them come here and try to protect the coastline! We need everyone's co-operation."
