I wouldn't know about this instance because whenever I see the words migrants and Daily Mail in the same sentence I don't read it. I did a paper at university on how the tabloid media exaggerate and falsify their reportage of migrants and asylum seekers. Needless to say the Fail and The Scum were the worst offenders. I'd advise reading more objective reports than those found in the Fail.

Wikipedia editors have said they will no longer accept links to Daily Mail stories to support citations because it is too unreliable.
A fiery debate on its suitability as a source ended with a consensus view that the Mail, and Mail Online, were "generally unreliable" and their use "is to be generally prohibited, especially when other more reliable sources exist".
The statement added: "The general themes of the support votes centred on the Daily Mail's reputation for poor fact checking, sensationalism, and flat-out fabrication."
