Excerpt:
A Muslim leader whose group planned to rally 5000 protesters outside a talk by anti-Islam activist Ayaan Hirsi Ali on the basis that she "condones violence and radicalises people" has previously met with a radical sheikh who promoted suicide bombing.
On Monday Ms Ali, a Somalian-born activist and refugee, cancelled her planned speaking tour of Australia and New Zealand, citing a "number of reasons including security concerns" and a "succession of organisational lapses" by event organisers.
She had been due to appear in Sydney on Saturday night.
Security agencies and police have reported no specific threat against Ms Ali.
