'reports' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.

'bastards besieging peacekeepers' is the wordplay.
'bastards' becomes 'sods' (I can't explain this - if you can you should believe this answer much more).
'besieging' indicates putting letters inside.

'sods' enclosing 'un' is 'SOUNDS'.

'of' is the link.
