The improvised explosive devices (IED) allegedly prepared by the accused gunmen in yesterday's horrific terror attack at Bondi Beach were "rudimentary", police have said.
Speaking at a press conference this morning, NSW Police Commissioner Mal Lanyon said the devices that were found in the accused's vehicle had been rendered safe.
He said the bombs has been fairly "rudimentary", and likely to have been triggered by a wick.

"I think they were fairly basic in terms of their construction," he said.
Lanyon said despite the bomb's rudimentary nature, they still could have caused significant damage if they were detonated.
"That's why we're investigating so thoroughly," he said.
"I'm very glad those devices were not activated."
