On top of all this bad news in Greece, the country has also received an influx of Syrian immigrants who came to Greece to escape their own desperate situations. (btw, my apologies for using a breitbart article, I don't particularly like Breitbart but this article is a nice summary of the syrian/greek struggle without any opinion.) On BBC radio yesterday, a tourist currently visiting Greece was interviewed. She and her partner were unaware of the Syrian immigrant crisis in Greece. She stated that one could see vast make-shift camps only a few blocks away from hot tourist spots and high-end hotels. They went to investigate and found that there was little food and water in the camps. The Greek are unable at this point to financially aid these immigrants. Tourist, such as the woman interviewed, are doing what they can to bring food, water and other resources to the camps.
That's unusual. I remember aid groups offering to help Syrian refugees in Turkey and running into all sorts of political problems and Erdogan's stupid stubborness. They would encounter no such obstacles in Greece, so perhaps it's the recency of the situation that's causing the problem.
I don't think it is as much of a neglect reason or that Greece does not want to help, it is sheer number of people coming into Greece and lack of aid to accommodate them. Greece has receive more than 63,000 immigrants from Syria and Libya so far just this year. More continue to come because it is safer to reach Greece by boat than Italy. There are many Syrian immigrants coming into Greece via Turkey, naturally the Greek government blames Turkey for not securing their borders. Dunno if this answers you question.
