In excess of 7000 migrants picked up entering the EU since Monday.
A higher number than before are unaccompanied 'minors'. Such would not have the means to pay the people smugglers, so are likely being sent ahead by their families for a better chance of being allowed in; the family will then demand to be allowed to join them.
The EU mandarins are running around like headless chickens with no idea how to tackle the problem.
