The statement in Arabic was posted last Friday on Arabic website alneda.com in response to criticism levelled at al Qaida for its role in the September 11 terrorist attacks on the US, Dr Gunaratna said.
It stated: 'We don't care about Western public opinion because it is for the Western people and in any case backs Western governments.
'Therefore it should not be a matter of concern for us whether western public opinion turns against us or not. We did this operation not for human kind but for Allah.'
