Greece's mishandling of migrant crisis under scrutiny by EU border agency.

Greece did not respond to an offer from the EU's border agency, Frontex, to send a plane to monitor a migrant boat that later sank with huge loss of life, according to EU border officials. At least 82 people are known to have died in the incident last week, but the UN says a further 500 may have drowned. The Greek coastguard has not commented on this latest claim that it did not respond to the offer of further aerial help from Frontex.
