Greek coastguard: 'Boats carrying migrants are overcrowded and unsafe'

Greece is one of the main routes for migrants making the journey into Europe.

The island of Lesbos, only a few miles from the Turkish coast, has seen an influx of nearly 200,000 refugees since the spring.

Jim Muir asked the commander of the Greek coastguard on Lesbos, Antonios Sofiadelis, why so many are dying on a short crossing that should be simple and safe.
