Whereever you use a name in DTML, the referenced object
is called, if it is callable.

In your case, you use the name "sequence-item" in the "dtml-let".
Apparently, your "news" instances are callable.
If I am right, then "x" is a string (which of cause does not
support cloning).

Try:

  <dtml-let x="_.getitem('sequence-item')">
    ....
  </dtml-let>
