Sydney cafe siege: Probe into gunman's asylum and gun licence
Australian Prime Minister Tony Abbott has announced a review into the background and security checks on the man behind the Sydney cafe siege.
Mr Abbott said questions must be asked about how Man Haron Monis was not on a watch list despite a history of violence and mental instability.
Speaking in Canberra on Wednesday, Mr Abbott said he had great confidence in the police and security services, but that he wanted "answers to some obvious questions that have been raised in the wake of this terrorist incident".
He said the authorities needed to know how Monis had acquired permanent residency in Australia, how he lived on welfare for many years while apparently physically able,
how he obtained a gun licence and "how someone with such a long record of violence and instability was out on bail".
