Peter Sutherland, the UN's special representative on migration, said he
was "amazed" by demands for economic migrants to be kept out of the
UK.
The 69-year-old also claimed the scale of the crisis is "exaggerated
beyond belief" and being "calculated to inflame tensions".
His comments come after widespread concern that the UK will be pushed to
breaking point as more migrants cross the Channel.
Up to 100 migrants roared as they stormed past helpless French police
officers near the Eurostar terminal to gain access to the tunnel last
night.
But Mr Sutherland added: "The first thing we have to do collectively is
to deal with their conditions.
"Instead of talking about sending Gurkhas or building fences, we should
be thinking of the humanitarian crisis." Express.
