Creatures bringing news about trouble starting (5)
I believe the answer is:
newts
'creatures' is the definition.
(newt is a kind of creature)
'news about trouble starting' is the wordplay.
'about' means one lot of letters goes inside another.
'starting' says to take the initial letters.
The initial letter of 'trouble' is 't'.
'news' enclosing 't' is 'NEWTS'.
'bringing' is the link.
(Other definitions for newts that I've seen before include "Kind of water lizards or efts" , "creatures" , "Small amphibians, efts" .)
