Online pest ran slurs, being hostile to people (13)

I believe the answer is:

antipersonnel

'hostile to people' is the definition.
(antipersonnel weapons are designed to kill people)

'online pest ran slurs' is the wordplay.
'slurs' indicates anagramming the letters (a slurred version of the letters).
'online'+'pest'+'ran'='onlinepestran'
'onlinepestran' with letters rearranged gives 'ANTIPERSONNEL'.

'being' acts as a link.

(Another definition for antipersonnel that I've seen is " Land-mine type".)

I've seen this clue in The Times.
