You can do this both for the cables themselves, and also for news articles, since they might be pressured by governments (or banks etc...) to modify their coverage, e.g.
 {{cite news | first= | last= | pages= | language =| title= | date= | publisher= | url= |accessdate=2999-12-31 |archiveurl= |archivedate= |deadurl=no}}
{{cite web| last =| first =| authorlink =| coauthors =| title =| work =| publisher =| date =| url = |format =| doi =| accessdate = |archiveurl= |archivedate= |deadurl=no}}
Some of the parameters are optional, you can leave them as they are. For a webcite copy, you need title, date, url, accessdate, archiveurl, archivedate, at least. To understand more about this, see: Wikipedia:Template messages/Sources of articles/Generic citations. 
Please also use check if your source has already been used, and use a repeat reference if possible, e.g. if the first reference is ..., then in repeat references (may be earlier or later in the text), use .   "
