The Australian Federal Police has cancelled an annual Ramadan dinner after Muslim community leaders vowed to boycott the event.

In a sign of deepening fractures between the Muslim community and Australian authorities, a petition was circulated on July 2, urging imams and other representatives to boycott dinners in Sydney and Melbourne because they were a tokenistic attempt "to create a false image of co-operation, harmony and trust which could not be further from the truth".

The invitation to the AFP Eid Dinner.

"I can't break fast with those who authorise flash bombs to be used against families," said Australian Muslim Women's Association spokeswoman Silma Ihram, who was one of 840 people to sign the petition.

The authors of the petition, a group called Concerned Muslims Australia, said police have targeted Muslims in "phoney raids" and the government has introduced legislation to "demonise, marginalise and victimise the Muslim community".
