smart phones, their identity cards. they've told me they have the phone numbers programmed in their phones of the greek coast guard should their boats get into trouble while making hour-long journey across the sea from turkey. and they even post distress gps signals on facebook to alert the greek authorities. so these are very coordinated, very organized migrants who are coming here to greece everyday. >> well, they need something going for them because we're looking at this video right now of these people that just came ashore and that is one crowded boat. so we're glad they made it safely and we hope that the trip onward will be a safe one as well. that man certainly is relieved. ivan watson talking with us. thanks so much, ivan. >> in italy, most migrants are coming there from african countries ravaged by war or some by poverty.
