Hundreds of migrants arrive in Greece despite EU-Turkey deal
As many as 875 refugees are believed to have made the crossing to Lesbos since the deal was agreed.
It could be "some time" before Greece deports any of the migrants that have been arriving on its shores as there is a clear lack of resources available to process them, according to Good Morning Britain reporter Jonathan Swain.
Speaking on GMB he said the "Greek authorities are so understaffed" that it a deal between the EU and Turkey, agreeing for Turkish authorities to take migrants back, may not be able to be implemented any time soon.
