Rising in singular haste (10)

I believe the answer is:

insurgency

'rising' is the definition.
(I know that insurgency is a type of rising)

'in singular haste' is the wordplay.
'singular' becomes 's' (abbreviation sometimes used in dictionaries).
'haste' becomes 'urgency' (I've seen this before).
'in'+'s'+'urgency'='INSURGENCY'

(Other definitions for insurgency that I've seen before include "Rising" , "Rebellion" .)

I've seen this clue in The Times.
